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?
That is referring to the launch, although it will be lower spinning as well. The updates on the new chart are how those shafts tested with the new 913 heads. You should see a slightly lower launch with the new D+ in the 913, which is why it is a great idea to see how that combination compares to what you currently have on a Trackman or other launch monitor.
