Graphite Design Tour AD GP Golf Shaft Review

Graphite Design Tour AD GP Driver Shaft

GDADGP_ImageThe Graphite Design Tour AD GP releases in a few days. New carbon fiber materials are being continuously developed. In the Tour AD GP, Graphite Design is using TORAYCA ® T1100G carbon-fiber pre-preg with NANOALLOY ® technology according their release information. This gives the shaft a stiffer tip without a change of weight that would typically be associated with tip stiffening by simply adding material.

    How will this compare to the di guys?

    • It is softer in the mid and butt and at the same time has lower torque. The profile looks like it will load easier yet deliver a slightly lower launch and spin.

        thank you!, how does this stack up to the MT? im currently using the AD MT 8x tipped 1″, would not tipping this at all be comparable or would it be a harsh difference?

        • If you have looked at the technical article on shaft tipping you will understand my view of tipping shafts that have ascending stiffness in the tip section. The MT turns up at the tip, you have removed stiffness and some of the stability intentionally designed into the MT tip.

          Looking at the raw profiles of the MT and GP 8x, The GP has a stiffer tip. Tipping the MT moved the apex of the softest section of the shaft from 11″ to 10″. I have had countless discussions with shaft engineers about tipping. They roll their eyes skyward when it comes to the practice of tipping driver shafts. Tradition in golf supersedes knowledge. Perhaps the practice goes back to designs that descended in stiffness all the way to the tip. Some of those designs still exist. The Aldila shafts for example. But many designs now use higher modulus carbon fiber, wire or other materials in the tip section. When you tip, you are cutting away some of this material.

          Back to your question. No amount of tipping will get the MT to the GP. The GP is simply designed with a stiffer tip section starting at 16″ from the tip. It remains so from that point to the tip.

    Coming from a DI 6X tipped 3/4″, what weight and flex should I be looking at? Looking to lower spin and tighten the dispersion of the DI. Thank you for he great info guys!

    • I would look at the 7S or X. Do not tip this shaft, the profile goes stiffer as you get closer to the shaft. You will be cutting away the stiffness designed into the tip.

    Can you explain the balance numbers? For example addi and adbb balance are in the 20+ range and the balance on this shaft is 1″ range. What does that mean and how does that make the shafts feel different? Seems like a big difference to me but not sure how it affects real world performance and feel. I really enjoy the feel and balance of th addi but definitely launch a little higher than I’d like and tip, while feeling great, does feel a hair loose to me.

    • Balance is the distance from the center the shaft balances. There is a lot of attention to producing high balance shafts now that head weights have crept up. To me, it is about being able to declare a club with a heavy head can be swing weighted. I do not have much belief that a system that was developed about 90 years ago has much science behind it. But, what do I know, the majority of the golf business likes it because it simplifies their ability to discuss some sort of specification they can all agree on. I don’t pay much attention to it most of the time. I use a club MOI device to evaluate dynamic load of a particular makeup.

    So if the AD GP plays a bit too stiff or launches too low, one could improve feel and launch by tipping it? I ordered an AD GP 8X for my driver (I like heavier weight) but ordered it 1/2″ longer than my current driver so I have a 1/2″ to play with on either end.
