I need to re-shaft my Ping G20 10.5 driver (good driver), the factory TFC169D Regular flex developed a crack, and it's out of warranty. While I'm at it I want to bring the trajectory down by using a L/M launch shaft and I'm torn between the Aldila NV55/Regular and the Fujikura Fuel 50/Regular. Specs on both are similar, and I had an NV65 in my older Taylor RX360 which worked well. I'm leaning towards the Fuji but a guy I play with makes clubs and he says the Fuji is no better, just more expensive, almost double. I never had a Fuji shaft before. Also, the tip on the Fuji is .335 and the G20 hosel is .350 so the Fuji will need a shim. Any opinions on which shaft might perform better and what difference will a shim make ?
