Aldila 2KVX NV Blue Driver Shaft Review

The Aldila 2KVX-NV series is popular with many of club fitters. While it is reasonably priced it does not sacrifice quality or performance. The NV Blue got overlooked when I reviewed the Orange and Green 2KVX-NV Driver Shafts. Aldila shafts are designed in fitting families. The 2KVX-NV follows that tradition.

the 2KVX-NV Blue is the mid launch member of the series. It is made of thin layers of high strength fiber. Those thin layers allowed Aldila engineers to craft linear designs without compromising torque or hoop strength of the shaft.

True Temper Project X PXV 39 Driver Shaft

By Russ Ryden, A Golf Digest America’s 100 Best Clubfitter

TTPX PXv39 ImageI have seen fair number of driver shafts with labels implying light weights, but I have only seen one shaft that was labeled with a number that actually was the weight of the raw 46″ shaft. The True Temper Project X PXv 39 is correctly labeled. The raw shaft is 39 grams. It is like holding a feather in your hands. When I start measuring a shaft I usually start with the EI profiles. With the Project X PXv 39 I started with radial quality. Surely a shaft this light was likely to have a low number. The number was shocking, the review samples were close to perfect. If you are going to make a shaft with walls as thin as they are on the PXv 39, they need to be perfect. This is a 39 gram shaft that can be oriented in any direction in a rotating hosel. It is the light weight version of the Project X PXv family of shafts.

While the torque numbers at first glance look high, they are as low as I see in shafts of this weight. I would not be putting this shaft in the hands of an aggressive high speed ball striker. However, at 6.4 to 7.0 pounds of butt stiffness, these are not wimpy shafts.

TTPX EIGjTb PXv39The bend profile is not uncommon for shafts in this weight range. I have had a lot of success fitting a similar profile in this weight range. The quick decline in stiffness in the high mid area, combined with a long stable tip section results in the launch needed in this weight range with good dispersion control. I am seeing this design in a number of high performance golf shafts.

TTPX PXv39 TipI have heard shaft designers discuss the weight of paint on ultralight driver shafts. There is no elegant glossy overcoat on the Project X PXv 39, every possible aspect of weight control went into this design. It is available only through True Temper Performance Fitting Centers. One look at the wall thickness of the tip and you will quickly realize this shaft should be installed by a competent club builder. High modulus carbon fiber are making designs possible that could not be considered a few years ago. The Project X PXv 39 is one such design.

True Temper XP 95 Iron Shaft

By Russ Ryden, A Golf Digest America’s 100 Best Clubfitter
Fit2Score, Dallas Fort Worth, Texas

TT_XP95_image
The True Temper XP 95 is the first of a new family of iron shafts from True Temper. It is an evolution of the GS series which it will be replacing. Like the GS family, it uses a special steel alloy which has higher tensile strength allowing for lighter weight designs. That alloy has evolved from what True Temper designated as S3 in the GS75 to S5 in the XP models.

True Temper testing and player feedback is addressing the low spin balls designed to deliver driver distance. Those balls do not spin enough to get distance and drop and stop performance on longer irons. To address this, True Tempers current generation of iron shafts are aimed at increasing spin. This is also addressed in the design of the Dynamic Gold Pro progressive launch model also releasing in 2014.

The True Temper XP uses a dual step pattern. Longer steps near the butt of the shaft, shorter steps closer to the tip. The longer steps. smaller changes in diameter per step, are called speed steps by True Temper. The shorter steps create a quicker loss of stiffness in the shaft as it gets closer to the tip. It is this property of the shaft that increases launch. That progressive stiffness loss can be seen in the EI bend profile.

I had a chance to talk to Bill Lange, the True Temper Director of Sales, at the 2014 PGA Merchandise show about the XP shafts.

The XP 105, available exclusively from Mizuno in 2014 is the first expansion of the XP family of shafts. I am told we will see both 85 and 115 gram versions in the near future.

Fujikura Fuel Golf Shaft Review

FUJIKURA FUEL DRIVER SHAFT

By Kirk James & Mark Vallier, A Golf Digest America’s 100 Best Clubfitter

Fuel_Image

The Fujikura Fuel shaft was introduced just prior to the 2013 PGA Merchandise Show and was named “the most talked about shaft at the Show”. The Fuel continues to create a lot of buzz in the print media and on the internet. Let’s take a closer look and see what all the buzz is about.

According to Fujikura, the Fuel is a low launch/low spin shaft designed for drivers, fairways and hybrids. The shafts are constructed with a series of high modulus carbon plies oriented at 45 and 90 degree angles in the butt and mid sections which their engineers claim reduce ovaling during the loading and unloading of the shaft. We have found through our testing and fitting process that the Fuel shafts are extremely stable with low launch and low spin characteristics as claimed by Fujikura.

Like many shafts, the Fujikura Fuel profiles vary with weight. As you will notice in the EI bend profiles below, the 50 gram shafts have a fairly soft overall profile with a relatively stiff tip. This stiff tip feature makes this shaft feel extremely tight and stable for a mid 50 gram shaft. We have found through our fittings that it will feel and play slightly stiffer than its flex rating. It is an excellent light weight option for a player that can load a shaft or that has a quicker tempo, or both.

The 60 gram, Tour Spec 60 gram and the 70 gram models have a slightly different bend profile than the 50 gram models. These heavier models are stiffer in the butt and mid sections, with a smoother profile in the tip section. The stiffer butt and mid sections make these models feel extremely stable (ie stiff) in the hands and give these shafts an overall stiff feel. The low torque of these shafts adds to their overall tight/stiff feel at impact. Our testing and fittings confirm that these are definitely low launch shafts.

The Tour Spec 70 gram S and X flex models have a very different profile than the other models. The bend profile shows a very stiff upper-mid section with a smooth but rapid decline in flex to the tip. These models are again extremely stable because of the stiff mid section, and are excellent choices for heavy hitters looking to lower ball flight in both drivers and fairways.

Our testing and fittings confirm that the Fujikura Fuel shafts definitely provide the low launch characteristics claimed by Fujikura. The 50 gram models have slightly higher launch and spin than the other models, but are still low for a mid-50 gram shaft. The design, construction and bend profiles of these shafts contribute to the overall stiff/tight feel that the player will experience when playing these shafts. The Fuel shafts are a good option to consider for a player looking to lower his or her launch conditions.

Oban introduced the Purple Kiyoshi in the fall of 2010, each year they have added a new profile to the series.  Oban’s goal was to make a high quality shaft, with different options that club fitters could use to the maximum performance out of players with different swings and needs.  As with any great shaft, we advise you go see a professional fitter to find the correct one for you to achieve the maximum  performance  for your individual game.

Oban on Tour

DevotedGolfer.tv editor Russ Ryden got to talk to Rich Parzych, Tour Representative for Oban at the Crowne Plaza Invitational at Colonial in 2013. Rich has spent many years on the PGA Tour as an owner operator of his own van and most recently at the Oban Golf Shaft tour representative.

Oban Kiyoshi Purple

Kiyoshi Purple was introduced first in the product line as Oban’s premium performance golf shaft. It is the highest launching shaft in the Kiyoshi line, offered in a weight range of 45-85g, The lighter weights are designed for senior and ladies flex available in the lighter weights. The Kiyoshi Purple is an extremely high quality mid launch/mid spin shaft. The 55g-85g all run the same EI profile, with similar torque. The torque ranges on all three Kiyoshi models (Purple, Black and White) are relatively low, The EI of the Kiyoshi Purple is tip stiff, extremely soft in the mid-section, and stiff in the butt. It’s a great shaft for average to mid-load profiles. With its stunning graphics, it’s difficult not to notice when a player has one in the bag.

Shaft Alignment

GOLF SHAFT ALIGNMENT

By Tom Wishon, Tom Wishon Golf Technology

This was copied from a discussion on another forum. It is the same as a private conversation I have had with Tom while researching the history of SST alignment.

“I was the guy that Dick Weiss came to back in 1996 after he had been doing his initial research into the effects of shaft asymmetry, when he wanted someone to verify what he was seeing in his initial work. Dick insisted that the result of testing we did for him was to be kept confidential. We honored that request.

But I can tell you that back then, while shaft makers were aware that their shafts did not have the same exact bending properties in all directions about the circumference of their shafts, they did not have any awareness of how asymmetrical many of their shafts were, and what this could do to shot performance for certain swing types.

So yes, shafts back then exhibited a very wide range of asymmetry. And in our testing for Dick, we most certainly saw that finding the most stable plane of bending in these asymmetrical shafts and then orienting that plane at the target line most certainly improved the consistency of the impact and ball flight. We even were able to orient certain shafts in a way in which it virtually made it impossible to hit a draw or fade.

This was a point that the USGA also discovered when Dick came to them to appeal for a conformity ruling for his process. The USGA did actually write into their rule concerining shaft orientation that it was only to be done to allow shafts to play as they were intended to be designed to play, and not to be done for the purpose of purposely influencing the flight of the ball.

Once Dick’s SST PURE process became more and more known, the shaft makers began to look more closely into this. Today, most of the better shaft makers do institute a test or tests on all of their shafts as a normal step in production. From this they position the shafts’ logo/name such that what they find under their test as a stable plane of bending is then oriented at the target when the shaft is installed logo up or logo down.

So today you won’t see as wide of a variation in asymmetry in shafts made by quality shaft makers as there was back when Dick discovered this and invented his process. But because every shaft maker has a “flyer shaft” here and there, there are times purely at random when a golfer might have a shaft checked and re oriented and see a difference in impact consistency on the face and a change in ball flight.”
