I gotta be honest here… I disagree with a lot of people on this subject I guess, but I think the "stock" shafts in a lot of the new drivers 2010+ are great in comparison. The myth that "stock" shafts aren't any good just isnt true anymore. Some of the tour guys are playing "stock" shafts. They have obviously been fit for it, but its no different than the one you can buy at the store. Other than the fact that it is shorter than what we buy "standard" in the store. Today's drivers are too long if you ask me. I had my Titleist 910D2 cut down 1" when I bought it.
TaylorMade, Nike, Titleist, Adams, Ping, etc... All come with really good "stock" shafts. And other than some of them having a logo printed on them somewhere, they are exactly the same as what you buy of the rack. In fact my Adams Speedline 9064LS came with an Aldila RIP alpha shaft, and before that I bought an Aldila RIP alpha to put in my PING G15. When put side by side you cant see or tell the difference, and you certainly cant feel a difference. I ordered my Titleist 910D2 with an Aldila RIP alpha as well, and again, you cannot tell the difference between any of them.
I see the original OP already purchased a new driver, but for those who are in the same boat and are reading this, here is the point:
GO GET FITTED!! The head is a sound & feel thing, but the shaft is the difference between gaining/losing yards and finding the fairway or not. THE SHAFT IS THE IMPORTANT PART!!
