Okay, so I have a 907 D2 10.5, I've only had it for two years. I bought it new even though it was out-dated. I've just really got control over it and fixed my mechanics to help with a lower score. However, today I went to the driving range to hit a few and after about five shots with my driver I heard a crack and noticed that the shaft (graphite) had a crack on one side running the length of the shaft. My question is this, should I re-shaft and keep playing with the driver I know I can hit well. Or should I bite the bullet and go for a new one?
