You should totally try the RIP Fairway shaft! If your driver is the 60 gram, try the 70 gram.

the other option you could go with is get S400. I was going to get X100 but when I was fitted at Titlelist, the S400 were the best choice. They are a bit heavier than the S300 but felt better with the weight.
Tony,
Two things to consider, and I'm basing this on experience with a couple Mitsubishi Diamana shafts.
