I have hit the dreaded part of getting older. Retired last year and still remain active but this golf season I have found that I have lost 2- yards from my driver. Rest of the bag has stayed relatively the same for distance. Bought new 716 irons last year and upgraded to graphite shafts and regular flex after playing with Project X stiff shafts on my AP2's for many years. That was an adjustment but love the flight and feel. Did an extensive fitting for these before settling on these specs. I am not a "Settler", my 714 D2 just has not been performing. Current driver shaft is a 60 gram Diamana Regular flex. We have a couple of demo days coming up in our area soon and was looking to try a different shaft. Any ideas? I confess I tried the TM M1 and hit it 20 yards better, but I am an old Titleist guy and want to stay that way. Help!
