what is the optiomum lanunch angle for a driver both myself and my mate have the same swing speed about 112 when we go to the simulator i hit it 40 yards further than him because i launch the ball about 12 to 14 degrees and he launches it 17 or 18 degrees we both have different drivers with 9.5 degrees of loft and have even when we switch the drivers we have the same results
Optimum angles (I think) are around 13 degrees so yours is best. His swing is obviously different from yours meaning he is putting more backspin on the ball and hitting it higher. He needs a fitting!
