If trying 3 different drivers and demoing a 910 did not include a fitting with either a launch monitor, or Trackman, Flightscope, where different shafts, head models, and lofts were tested and compared, then it's really an opportunity lost. I have vowed to never buy clubs without going through a fitting that includes actual outdoor testing on the range.
My latest Driver, broke my Ping G15, is a 910 D3 8.5, playing it at 10, with a spin reducing RIP 60 stiff shaft. After playing it for a few months, I went to a Titleist Demo day to try and cure my 3 wood. Stiffer heavier shaft is working nicely. The Titleist rep suggested shortening the Driver to 44.5. He told me what port weight to order. I cut it, put the grip back on and installed the heavier weight. Swingweight is roughly the same as before and control is better.
I've been fittedt three times now in recent years. On Trackman it becomes very clear that each combination produces different results. My Seniors league contains a bunch of 90 mph or less swing speeds, yet there they are with a Driver they can't hit. They hit their 3 wood or 5 wood much better, but the ego gets in their way.
