Looking for a little advice for my new driver. Currently own a 910 D3 with the Ahina '70 Shaft X Flex. Looking at ordering a new 913 D3 with the Ahina 80 X flex, and was wondering if tipping the shaft would help increase the overall stiffness of the shaft. It was suggested to me to tip the shaft to decrease the launch angle and spin rate. I love the combination I have right now, but would like some more info.
