Diamana Blue S+ Driver

915d2-driver
The stock shafts in the 2015 Titleist 915 drivers include the Diamana Red, White and Blue models. This year, unlike last year, they have the same appearance as the original Diamana shafts, a silver background with the Red, White or Blue Diamana logo. And, with the exception of a very slight increase in torque, they are identical to the legacy design.  We have received review samples of the Blue and a few of the Whites. The remainder of the Whites and the Reds will be added to this review when they arrive.

The Blue Diamana is perhaps the most copied driver shaft design I have ever seen. It is a good fit for golfers with a quick swing and a hard transition. The profile has a soft mid in relation to the tip and butt. The Diamana + models are available as options from most companies in 2015. Many, at no upcharge.

Oban KIYOSHI Tour Limited Golf Shaft Review

OBAN KIYOSHI TOUR LIMITED DRIVER SHAFT

Kiyoshi Tour Limited Image

The latest model from Oban Composites is the Kyoshi Tour Limited.  Released in 2014, this high modulus composite shaft features a tip section that is stiffer than all of the other  Kyoshi models.  Looking at the EI bend profile of this shaft, the shaft maintains it’s stiffness to about the 15 inch mark, then drastically softens and maintains that softness through the shaft to the butt section where it stiffens again around the 33 inch section.  We used the 60 in 04 (stiff) flex.  This shaft in the 60 and 70 stiffens in the butt section to produce higher launch conditions without increasing spin rates.   We took the shaft to the range to test it out, and came back with some profound results.

Oban Kiyoshi Gold Golf Shaft Review

OBAN KIYOSHI GOLD DRIVER SHAFT

By Tony Curro  –  Tru-Fit Custom Clubs

Kiyoshi Gold Image

The OBAN Kiyoshi Gold Driver shaft was introduced in 2014. It is the latest and perhaps the last we are told, of the Kiyoshi family of shafts from Oban composites.  This high modulus composite shaft features a tip section that is softer than all of the other  Kyoshi models.  Looking at the EI bend profile of this shaft, the shaft maintains it’s softness throughout the shaft into  the butt section when compared to the other Kyoshi models.  We used the 65 in 04 (stiff) flex when testing.  Although this shaft didn’t seem to be a perfect match for our tester, it did give us some interesting data to look at.

Aldila Tour Blue – Aldila Tour Green Golf Shaft Review

Aldila Tour Blue and Green Driver Shafts

Golf Digest 2013 Americas 100 Best transparent.fwMeasurments By Russ Ryden, A Golf Digest America’s 100 Best Clubfitter

Testing by John Dranshak
Dead Solid Perfect Golf Clubs, Columbus Ohio

The Aldila Tour Blue and Aldila Tour Green have now been with us for about a year and this review was first published last year. It has been updated with testing by John Dranshak, a club fitter that has been using 3 point EI profiles to guide his fitting process. These shafts are noted by Aldila as being made from ultra thin carbon fiber. This technology was first introduced in the Aldila NV and was unique in its day. Most premium shafts are now made with multiple layers of thin sheets. In my memory, Aldila pioneered this technique and a look at the radial consistency of these shafts shows what can now be accomplished in the mid price range ($250) of premium golf shafts. The shaft to shaft bend profile consistency of the Aldila Tour shafts is very good. You can be confident your shaft will be a very good match to the shaft you were fit with.

Aldila Tour Blue

The Aldila Tour Blue is an impressive classical design, soft mid in relation to tip and butt. Outstanding radial consistency, average 99.3% with a 0.5% standard deviation. This shaft is available as an option from most club companies.

Aldila Tour Green

AldilaTourGreen_ImageThe Aldila Tour Green was in play on the PGA Tour at the end of the 2013 season. I saw it often on video coverage. A low launch design created with a soft trough at 26 inches and a stiff bump at 18. Not an uncommon design but new in the Aldila lineup. The reinforcement you can see in the tip section creates flat deflection below the mid-high maximum bend point, creating a lower launch. The Aldila Tour Green is one of the stock options in the Titleist 913D2 and the Titleist 913D3 drivers and can be found in many of the Titleist fitting carts.

Simulated Deflection Loading

The new addition to the Fit2Score software renders simulated deflection under load and unload as it might happen during a golf swing. It is a very unique tool for understanding the performance of a golf shaft. The ability to model performance of a golf shaft is created by the 3 point bending shaft instrument used by reviewers on this site.

Performance Testing by John Dranshak

Player testing was performed at Golftec (Easton) in Columbus, OH by Joe Stago PGA Professional. Joe tested the Phenom Nasty Long, RIP NV, and standard NV shafts earlier this year and is familiar with the Aldila line of shafts. The shafts were paired with Adams XTD heads including Driver, 16.5* fairway metal and 20* and 23* hybrids.

Graphite Design YS Golf Shaft Review

Graphite Design YS Reloaded Golf Shafts

GraphiteDesign_YSReloaded_Image

The YS Reloaded is a updated version of the Graphite Design YS+ featuring better materials, 50 gram versions and new graphics. The profile, a classic, soft mid in relation to tip and butt is largely unchanged. This profile is available from every major shaft brand at many price levels. A bundle of YS+ shafts were in the shop that had never been reviewed. That presented the opportunity to compare the origional YS+ to the 2015 YS Reloaded.

Graphite Design YS+ Golf Shafts

GraphiteDesign_YSPlus_Image

In the YS Reloaded, the point of maximum bend in the shaft is moved up slightly toward the butt to accommodate the heavier heads that dominate the current market. Newer materials deliver slightly improved hoop strength as well as more consistent hoop strength down the length of the shaft.  In the 60 gram models the 2015 YS Reloaded has slightly lower torque. The 70 gram versions are much the same as the earlier YS+
