Graphite Design Tour AD DI Golf Shaft Review

Adam Scott won the 2013 Masters playing this shaft in his driver and Tiger Woods has been using it for about two years now. Stacy Lewis is now using it. On any given week, there are 10 to 12 in play on the PGA tour. There is nothing like PGA Tour success to draw attention to a driver golf shaft. The requested box full of review samples appeared at my door last week and I was anxious to understand what is making this shaft popular on the PGA tour. I do not have any experience with the shaft yet, so lets look at the numbers.

    Russ, interested in your comments regarding the AD DI and the possibility this shaft could help with a negative angle of attack. I too struggle with this with my driver. The facility that I work with has a limited number of shafts on hand that I can test. Just got a new Ping 30 and I’m trying to do my best to find something that will help my AoA numbers. I’ll have Flight Scope data with the G30 next week, any recommendations?

      The only cure for a negative angle attack is a good swing coach. That, and a lot of practice working on path and regrooving your swing dynamics. I have the coaching, but I am just not putting in the range time to fix my negative angle of attack.
      So, can a shaft with this design mitigate the problem? Short answer, yes. Over the past few months I have used several profiles in my driver that are similar to this design. My launch and distance are improved. But, read on.
      I am currently playing a 50g X flex. I know from picking up many, many clients irons and swinging them to get a sense of what they are use to, that a club which is heavy in my hands will dive into the ground. To hit them, I have to exaggerate my hip turn to flatten my swing. So, I went to a lighter shaft and took a little weight out of the driver head. And, added a pronounced hip kick to the beginning of my driver swing. Its working, but I have not yet put myself on FlightScope to validate the result.
