Graphite Design Tour AD GT Golf Shaft Review

GD TourADGT Image
GD AD BBvsGT EIReleased in 2013, the Tour AD GT is intended as a higher launching design than the Tour AD BB released in 2012. That was confirmed in our range testing when the proper weight and flex were used. The torque measurements were right between the Tour AD DJ and the Tour AD BB.  The bend profiles are consistent from shaft to shaft. The Tour AD GT like the Tour AD DJ have slightly stiffer midsections as the increase in weight and stiffness.  This is different from the Tour AD BB which maintain exactly the same profile from weight to weight, and flex to flex.

    Whao! Fantastic info. I am sure this will help many golfers..Great Work!

  • JJ

    Excellent info guys! Thank you for providing this very useful (and hard to find) info!

    Hello Russ,

    The link for the complete FlightScope Report seems to be dead. Webpage says: ”

    404 Not Found”.

    Could you please repair it?

    Thank you very much

      There is some issue with the server that we are trying to understand. Its not broken, just very slow at times.

    I think I don’t clearly understand the difference between the Enhanced EI Bend Profile and the Bend Profile Signature.

    Correct me if I’m wrong: the Bend Profile Signature graphic magnifies the bend profile of the shaft, which gives us a more evident/meaningful representation of how the model bends (more pronounced curves).

    If so, why in the Bend Profile Signature chart comparing the four Graphite Design TourAD Shaft models, the BB seems to have a softer tip and butt compared to the GT, while in the Enhanced EI Bend Profile graphic at the beginning of the article it seems to be the opposite?

    Also could you explain why on the Enhanced EI Bend Profile graphic we go from 6 (inches?) to 40 and in the Bend Profile Signature chart it’s from 1 to 34?

    I ask because as I’ve read all the articles now, I think I miss some important concepts …

    Thank you very much

      I think I get it, if you watch at 34 in the Enhanced EI Bend Profile graphic the GT is stiffer than the BB, and I see that it’s the same in the tip: at 6 in the Flexural Signature graphic the BB is stiffer than the GT but at 1 it’s the GT that is stiffer.

      Sorry for the dumb question …

      By the way, those tiny differences are maybe not meaningful. Would you say that when we look at a flexural signature graphic we can forget the very end of the tip and the butt? And just look from let’s say from 5 to 34?

        I wrote an article at the beginning about Signature. I have called it different things at different time. There is no word in the shaft business for the concept. This is a link to the article:
        The scale on the graph you were looking at was 34″ for no good reason, just what happened that day.
        What I call signature is the change of stiffness from one point to another. I measure inch by inch, so it is the change in stiffness between 40 and 39, then between 39 an 38, and so on. If a model is consistent from weight to weight and stiffness to stiffness, then the signature graphic will be the same for all the shafts. It is not absolute stiffness, but rather relative stiffness within the shaft. And the shafts that are easiest to understand for a fitter are consistent within the model.

        How a shaft loses stiffness is to me, more revealing than the absolute stiffness. It is a microscopic view of the profile where change is amplified. On the other hand, looking at the overall deflection profiles as I am doing in the most recent reviews is the opposite. It mutes the stiffness aspects into a smoothed graphic. This smoother view is how the shaft actually bends under load.

        The differences in the Graphite Design shafts result in different feel and slightly different flight if you are sensitive enough to perceive the feel and consistent enough to see the flight. The understanding of feel and flight can only come from spending time with a fitter that has a wide range of shafts that can be connected to the same head. You might say it is an acquired taste, much like learning the differences in fine wine. You have to learn through personal experience. Find a well equipped fitter and buy some shaft appreciation time.
