My current driver is the Titleist 910D2, which has the adjustable head. Of the Titleist drivers, it's the most forgiving. I hit it pretty decent, but honestly didn't pick up too much yardage over my old Taylor Made...maybe 5-10 yards on average. The adjustable head does make a difference, because there are a couple configurations that I flat out can't hit. lol. But what I have found is that I find the configuration that I hit best and never change it, in which case the adjustable head was kind of pointless for a player like me. I have old Titleist 908F fairway woods that I've yet to find anything new worthy of replacing them with.

Everything in my bag is a Titleist, except for my putter...but if I had it to do over again, I might have just stuck with Taylor Made for the big gun. I like my driver, but am not in love with it. I think you get to a certain point with technology where a driver is a driver and it's just more about how it feels and looks to you...much like expensive fishing rods.
