I recently bought my 910D3 with a Project X 5.5, as I was fitted between a 5.5 and 6.0 at a local pro shop. I hit some balls in front of my club pro today with it and he said I am more a 6.0 to 6.5 more towards the 6.0, I was wondering if there is anywhere I can buy a Titleist Project X 6.0 shaft for my 910? I'd rather not buy an actual $275 Project X shaft from a retailer.
