I knew I was behind the times playing my 710MB irons with DG S400 shafts, but after my fitting today I have a lot to look forward to! Thanks to my Titleist fitter Steve Creekmore we settled on the new T150 with Project X LZ 6.0 shaft. The numbers were great and the feel was better than I expected. The sound will take some getting used to but I can live with that. Highly recommend taking advantage of a Titleist fitting specialist, even if you have to wait a little longer when living in Montana.
I also will be retiring a 917D2 as the new GT2 was too good to pass up!
