I really think that a good fitting is your best path to a driver that works right for you and your swing.
I know absolutely nothing about your local Golf Galaxy. I believe that some stores of that kind (Edwin Watts, Golfsmith, etc.) have good fitters. I also am pretty sure that some of those kind of stores have guys that have been sort of instructed in how to do a club fitting in the manner that store chain likes. I seem to have encountered some who are pretty focused on making sure the perfect fit for me just happens to be the very clubs they happen to have in stock at the moment.
Then there are real professional fitters. I think Taylormade calls their better authorized fitters Performance Labs. Titleist calls 'em Advanced Fitting Centers. My advice: Ask around, your local club/course pros likely know who the really good fitters in the area are. It is worth a drive to find one, and honestly I think I would pick my brand of club based upon what the good fitter works with rather than picking a brand and then trying to find someone to fit me.
That's not an answer to the question you asked, but I think it's a good solution. Personally, if I was flying drives 275 I'd sleep with my old driver, but whatever...
