Currently play a 910D3 with an aftermarket shaft that I love. I don't change equipment often, but I'm wondering if it's possible to get a 915D3 head, either direct from Titleist or through a rep? Would love to try the latest technology but can't see purchasing a shaft that will likely end up serving only as an expensive alignment aid. (I've got enough of those lying around.) I know I could get one on eBay easy enough, but I would feel much more comfortable dealing with Titleist direct.
