Currently I am using a senior shaft in my clubs. I tried a driver with a ladies shaft and I am hitting them out of site and accurate. I am 67 years of age and have been a single figure golfer. I am only short 5ft 6 ins. about 70kgs. WHat is the difference in the shafts. Our local pro who is a sponsored Titleist fitter etc suggested I try the driver.I am interested in what the subtle difference is in weight etc.Thank you.I think the NXT Tour is a great ball.
