I am looking to possibly swap out my Mizuno MP 63 heads on a set of KBS Tour 120 Taper Tip Shafts. My question is what is the Bottom Bore to Ground measurement on the TS-1 and the DBM as compared to the MP 63? I am hoping the current shaft with grip would not need to be altered to play to the current length I have them set at. Also, I am assuming I would just need to purchase shims for either build?
