The Graphite Design Tour AD CQ will be available in January 2023. It is the first carbon fiber shaft to utilize Nita 2G NAMD used in tennis racquets. Carbon Nanotube is bound into high modulus graphite fiber. The fiber quickly snaps back to promote a higher degree of energy transfer. The 2G-Namd fiber is used in the butt section of the shaft. I see a unique EI profile I have not seen an any other currently available driver shaft.

When I looked at email this morning there was an announcement from Oban that the AirBurst shaft is now available. I called Ralph for review samples and he told me the protos I had measured last year were the final versions. Much to my delight I was not going to have to spend a half day measuring shafts for the knowledge base and this review. When the TaylorMade M3 arrived in January it went into my bag. Over the last few months I have played a number of 50 gram shafts. The AirBurst was in the bag last month and between storms and cold weather it got played for a few rounds.
Over the years I have learned that light weight driver shafts are not created equal. The lighter the shaft the thinner the walls. Thin wall driver shafts without premium material play like wet noodles. You can hit them straight by slowing down your swing and waiting for the head to show up. It is like a bunt. With a little practice, you can get the ball to go straight. They are actually a good training tool if you are out of sync and need to get your feel back. But should you go after the ball, there is no telling where the head is or how it will be positioned at impact.
Then there are the premium shafts made with high density thin ply prepreg. The thin sheets let the designer use enough bias plys to stabilize torque. With enough torque, the head will be aligned with your hands at impact. Then, the light weight shafts let those of us who’s swing speeds are age challenged get our speed back. Define the term “premium light weight shaft”? In dollars, the definition has become $700+. Add a head and we have an $1100 driver. For the record, I am currently alternating between two 50 gram shafts in this price range. And I have not missed any fairways over the past two months.
Ralph and Woody start the discussion about the Oban Airburst driver shafts at the 5:15 mark on this video shot at the 2018 PGA Merchandise show.
Lets take a closer look at the Oban Airburst.

Aerotech steel fiber iron shafts are the only graphite shaft that have been consistently played on the tours. The shaft is unique, a thin steel wire is wrapped over a filament wound graphite core. The filament wrapping process, done correctly, creates inherently round shafts by eliminating any possibility of a sheet overlap that can occur in sheet wrapped designs. Until now, this design was limited to iron, hybrid and fairway shafts. Steel is heavy compared to graphite. Too heavy to produce a long driver shaft in the common weight ranges. That problem was overcome in the Aerotech Ti-Fiber driver shaft by using Titanium wire in place of steel.
Listen to Chris Hilleray, the owner of Aerotech explain the shaft at the 2018 PGA Merchandise show.
The TI-Fiber driver shafts wrap a braided titanium wire over a filament wound carbon fiber core. This process is explained in greater detail on the Aerotech website and explained in the Aerotech SteelFiber constant weight taper shafts review.

Mitsubishi Rayon has expanded the braided OTi iron shaft into a constant weight tapered shafts. This is explained in greater detail in the review of the OTi Parallel shaft The OTi shafts starts with a new form of prepreg they call Tow. The carbon fibers are arranged in bundles, the way a steel cable is made. The bundles are impregnated with resin and then woven into a braid. That braid bundle is then slipped over the mandrel. You might think at this point no spine. There is a common misconception that spine is caused by sheet overlap or welds. My experience is that it is the result of roundness or more specifically lack roundness of the shaft. In carbon fiber, that is mostly caused by outer wall sanding. The redial consistency numbers show below the measurement charts rates this important quality consideration.

This is the second release of a Diamana Thump Iron Shaft. The first release, in 2010, was eventually discontinued. At $160 per shaft, or $1280 per set of shafts, there was little interest. I am surprised to see the shaft again being offered. Perhaps PXG’s success at selling uber expensive irons demonstrated there is a market for ultra premium irons.
What exactly do you get at $160 per shaft? Much like an exotic sports car you get light weight strength. I am seeing equivalent steel stiffness with 10 to 15 grams less weigh. I am not referring the the R,S,X denoted on shafts. Those letters are meaningless ways to compare shafts outside of their own particular model. I am referring to area under the EI curve, the only functional method I have seen to rate shaft stiffness. I have to get into the 125 gram range in steel to see a stiffness match to the 2018 Mitsubishi Chemical Thump 105 gram iron shafts. These are truly exotic iron shafts at a truly exotic price. Unless you are comfortable with the stiffness found in something like a 125 gram KBS tour this is not a shaft you can load. But if you are, you have to see what happens when your clubs weigh loses 15 grams. Let’s take a closer look at the numbers.

The introduction of the Dynamic Gold 115 Wedge shaft is yet another event recognizing the trend toward lighter clubs and shafts. The Dynamic Gold Wedge shaft is 130 grams, the Dynamic Gold 115 sheds 12% of the traditional weight. It is time to refresh the 2014 article about Dynamic Gold wedges, putting the Dynamic Gold 115 into perspective with the other TrueTemper wedge shafts.
