Hi I’m looking to put another tour ad di 8x shaft in my driver. I had one previously in my 917d3 but had changed it out, well I’ve got another one coming ina nd was wondering how much it should be tipped, the previous wasn’t tipped, but was always alittle soft. My swing speed averages right around 117 mph and I carry it on average about 290. Any answers would be greatly appreciated. Thanks in advance.
