today, i was looking to make a trial change on my 915D2. It's currently set for D-4. My initial thought was to just move to C-3 to give a small draw bias. I was surprised to see that although the top adjustment was movable ("D"), the bottom adjustment ("4") was fixed. This results in the shaft being turned. Therefore, unless you are using a blank grip, the grip will now appear shifted when lining up the club. I saw this on my old non-Titleist driver that was not very adjustable.
Any reason why Titleist doesn't have both adjustments move to eliminate this? I'm sure with all of the R&D, there must be a reason.
thanks in advance for your comments.
