I was fit for the diamana ahina 72 x-flex and a 10.5 loft on my 910D3 which i thought was ridiculous because i had always played an 8.5 but its hard to argue with trackman. I ordered it and have never looked back. great combo.. my question is when it says "low-mid" is that spin and launch? my concern is if i order my 913D3 with the new D+ white 72 the launch will be lower because according to the shaft chart in custom club options the spin is similar but the launch will be lower. is this stock shaft change because of the increase in ball speed with the new driver?
