We are all looking for the perfect cue with the perfect shaft for that perfect game. I have lots of cues and many shaft for each. The game I play determines the cue and shaft size and tip I use. If have two or more shafts you can change tips on them to experiment so you can improve your game. A good shaft will last longer than you will or until a better shaft comes along. I have a 40 year old shafts that still play great, but is 2 inch to short for my current playing style. P.S. I have never played with a 10mm tip maybe someday. Hope this helps. Good Luck.
