I will be buying this club in the near future, I know it is the right club for me, period. Have 2 - 910 hybrids, Blue Diamanna-80 S shafts. Bought the 3-wood this year with the Blue Diamana-72 S shaft. Great club. My driver swing speed was measured mid 90's, and was told this speed is on the "cusp" between R and S. I swung both shafts, had better distance results with the 9.5 S, and was told launch angles were in the window. I'm a senior, but can still hit a good one 240-250. Feel confident with S shaft. Input, please. Thanks.
