I'm thinking adjustment like Cobra (sister company) 3 way adjustment of the head, but I really don't want to see adjustable weights. I like the purity of the Titleist drivers without all that Taylor Made junk hanging off of them, but there must be something big coming.
Also don't like the triangle shaped head (e.g. 907D1), so hopefully, we will keep things pear shaped, but make them really sweet with a minor head adjustment and LOTS of shaft options, especially on the higher end. I'd also get RID of the "Exclusively for Titleist" shafts. They just get yanked out by serious golfers and replaced with REAL OEM shafts.
