It has been some time since I measured a set of UST Mamiya Recoil iron shafts. UST does not make review samples available and the last time I did measure a set of constant weight taper Recoils I did not see consistent profiles through the set. Updates to a fitting cart that arrived a few weeks ago included the Recoil ESX. I ordered a set of irons that were getting custom shafted with uncut ESX shafts to get an updated look at set consistency. I pulled the shafts and measured them. I was suprised with what I saw.

UST Mamiya ATTAS 5 GoGo Driver Shaft Review

UST Mamiya ATTAS5 GoGo Driver Shaft

USTMamiya ATTAS5Image

TourSPXTransparetLogo.fwThe UST ATTAS5 is the late 2013 addition the the ATTAS family of shafts. It compliment the ATTAS3 and ATTAS4u reviewed earlier. The ATTAS shafts are ultra premium models made from ultra-high modulus, low resin content materials. They are available from UST Mamiya Tour SPX certified fitters only.

USTMamiya Attas3vs5I see in the ATTAS 5 a design that keeps showing up in new shaft releases. A steeply descending profile showing a rapid loss of stiffness from butt to tip, with a long stiff tip. The difference between one brand and the next is the rate of stiffness lost and the length of the tip section of the driver shaft. The new ATTAS 5 and the ATTAS 3 released a few years ago are a good high launch vs low launch pair. The 6 Stiff profiles are compared in this illustration. The ATTAS 5 is softer in the mid section. It will create good launch and spin for a golfer with a flat to negative angle of attack. The stiff mid ATTAS 3, fitting the player with a positive angle of attack, looking to create a lower spin penetrating ball flight. The ATTAS 5 design is a good compliment to the low launch, low spin heads and balls that are common in the 2013-2014 marketplace.

USTMamiya ATTAS5RadialWhat struck me as I measured the ATTAS 5 GoGo review samples was the radial quality. Several of the shafts had perfect radial quality measurements. So perfect in fact that they showed very little change in oscillation patterns in any orientation. That prompted me to take a hard look at the 8 stiff shaft. The red lines in this illustration show the Flat Line Oscillation (FLO) planes. These indicate the high and low points of stiffness around the shaft. On a perfect shaft such as this, they did not fall 90 degrees apart as is typical. The Bow plane of the shaft was not a point as shown on the graphic, but rather a 50 degree range, centered at the spot shown, that indicates a shaft which is not only perfectly round, but also perfectly straight. Shafts such as this show us what is possible with current production technology if you are willing to spend $605. If you have a rotating hosel the ATTAS 5 GoGo shafts can be orientated in any direction with no regard whatsoever for alignment.

USTMamiya ATTAS5 FLOIf you are not a club builder you may not be familiar with the term FLO. It is located by clamping the butt of the shaft and attaching a weighted laser pointer to the tip. These images are a 5 second time delay photo of the laser tip oscillating. As you can see, the oscillation follows the stripe on the board perfectly in both planes. This simple technique quickly finds the hard and soft planes of a golf shaft.

The clamping device is a laser detection instrument that measures the oscillation rate of the shaft. This is called the frequency of the shaft. It is a method of measuring stiffness. FLO DisplayFrequency matched shaft sets are made using this equipment. By comparing the frequency of the two FLO planes, the radial consistency of the shaft is quickly determined. If the frequency on the two FLO planes are the same, or nearly the same, the shaft is perfectly round. The UST Mamiya ATTAS 5 shafts are perfectly round.

This photo shows the clamp with a radial protractor attached to the shaft. The tip points to a board with a vertical line, That line guides the deflection perpendicular to the clamp. Suspended above the shaft is the camera used to take the photos and video for this short demonstration of shaft oscilliation

KuroKage Silver TiNi Driver Shaft Review

Mitsubishi KURO KAGE Silver with TiNi

KuroKageSilverTiNiImageThe Mitsubishi Kuro Kage Silver has been updated in 2013 with the addition of 8 inches of Titanium Nickel Wire wrapped into the tip section of the shaft. The graphics are slightly different and the tip bears the TiNi logo used on Mitsubishi shafts with Titanium Nickel wire tip reinforcement. The KuroKage line was the first of the Mitsubishi products to use high density pregreg, The Kuro Kage shafts have this high density material added to the lower third of the shaft.

KuroKageSilverTiNivsFubukiKThe EI Bend Profile Signature is similar to the Fubuki K. The Fubuki K and its predecessor, the Fubuki Tour continue to stiffen from 11″ to the tip, while the Kuro Kage Silver softens. Both have a slight mid zone stiffness bump, like the Diamana White Board with that bump occurring closer to the tip in the Kuro Kage Silver to promote a little higher launch.

KuroKageSilverTiNiEiGjTb
While this is a mid priced shaft, $300 MSRP, in the Mitsubishi family of golf shafts you would not know that by looking at the radial quality. I cannot ever remember having 6 shafts in my hand that at most, varied by 1 CPM from hard to soft plane. Awesome. In a marketplace where every driver shaft has a rotating hosel, we should expect no less. And this shaft proves the manufacturing technology exists. What we do see in the Kuro Kage Silver TiNi is slightly higher torque in the R & S flex models than the Diamana and Fubuki series. Evidence of player profiling design, the players using the R & S will load the shaft less and get more feel from higher torque. Those using the X flex models need the control of low torque.

KURO KAGE SILVER Range Test

The difference between the previous version of the KUROKAGE Silver and the 2014 model is the addition of 8 inches of Titanium Nickel wire in the tip section. That gave us an opportunity to test the fiber by comparing the two shafts with a PGA tour quality ball striker, Mark Maness.KuroKageTestAverages
As you can see from this composite FlightScope report, the TiNi material did indeed add distance, reducing launch and spin with a slight increase in club head speed. Mark commented during the tests that the tip of the Kuro Kage with the TiNi felt more stable. That in a shaft with a softer tip than he has in his gamer. Its always nice to see that a technical improvement in a golf product actually results in improved performance and is not just more marketing hype.

Grafalloy BiMatrix Tour Prototype Golf Shaft Review

Grafalloy BiMatrix Tour Prototype

Bubba Watson plays the Grafalloy BiMatrix driver shaft and won the 2012 Masters with it. When he came on tour he showed up with one painted pink. Grafalloy accommodated him and made them in pink. For those that are not ready to play with a pink driver shaft it is also available in baby blue.

This design was introduced about 10 years ago and I tried it at the time. It was black back then and I still have an original R in the shop. I profiled it a few years ago and was surprised at the profile. It looked like a high launch design. The R flex profile from the original looks like the X flex I just profiled for this review. The current R & S flex have been redesigned for the typical R or S player.

Project X PXi Golf Shaft Review

Project X PXi Iron Shaft from True Temper

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

ProjectX_PXi_imageTT_PXvsPXi_EiIron shafts are getting lighter. Lighter means faster, it means more maneuverable. Think of the difference between a Carbon Fiber Lamborghini and a Heavy Metal Chevy. The light weight Lamborghini accelerates quicker, there is less weight to get moving. It corners quicker because it has less centrifugal force acting on it. The Project X PXi is a lighter faster Project X. The 6.0 model lost 12 grams of weight and 2 pounds of butt stiffness. Does it work? Ask Jason Dufner and Ian Poulter, they are both using it. And we have Tiger and Rory using it in their utility/driving irons.

Loss of weight typically means loss of stiffness. As you can see, the average stiffness profile of the PXi is softer than the average stiffness of the Project X. Once again, we see stiffness numbers on a shaft that do not indicate an absolute reference. Do not take that comment as a criticism of True Temper. It is the same scheme used by every shaft company. That is one of the many reasons that club fitting is so critically important to game development.

Project X Golf Shaft Review

Project X Iron Shaft from True Temper

ProjectXImage

The Project X design is different from the stepped shafts designs made by True Temper. The EI profile is constant from flex to flex, The stiffness increases as the shaft weight increases. The numbers on the shaft, 5.0, 5.5, 6.0, 6.5 and 7.0 represent stiffness. They are a patented numbering system that dates back to FM Precision. Frequency of the shaft was translated via a linear formula into a stiffness numbering system. A 10 Cycle per Minute, CPM, difference equated to a stiffness number change. When you hear the term frequency matched shafts, it refers to a system, not necessarily the original Braly system, of matching iron set stiffness.

Here is a little history if you are interested, Union Hardware was the first manufacturer of steel golf shafts in the US in 1924. They were acquired in 1956 by Brunswick, which also owned MacGregor golf. Brunswick supplied blanks to FM Precision, a golf shaft company owned by Kim Braly and his dad, Dr. Joe Braly.  In 1986 Brunswick acquired FM Precision. At some point, the name was changed to Royal Precision. In the early 2000’s Kim Braly designed the Project X and it quickly gained wide acceptance on tour. In 2006 True Temper acquired Royal Precision and the Project X brand.

The Project X is a classic, with too many tour wins count. Until competitive designs emerged, it was for many good players, the shaft of choice. Radial quality and shaft to shaft consistency in the shafts I have checked is excellent. The Project X can be installed in any orientation, being nearly perfectly round, orientation will have no affect on the play-ability of the Project X.
