I have 60 in driver and 70 in 910f 15 deg.  I is low launch with a powerful flight.  For me and I have only gamed it once and practiced with it once, it needs really low tee, lower than the 909.  Defo feels stiffer but still not boardy than the for Titleist Diamana stiff I had in the 909 F2.  I will have some better launch monitor data in a couple of weeks as I am setting up a fitting shop.

In the 910F 15o 3-wood, factory Titliest has been recommending the heavier weighted shaft in the 3W. But, I recommend a Titleist rep fitting for the best outcome.
