I have a Callaway RAZR X Black Ti 10.5 driver head and I need to find a good shaft to put into this head
There are a lot of good shafts that could work. I would need some details about your game, like club head speed, tempo, trajectory preference, etc. and what you are looking for in performance, like more distance, control, both… Also, how much you are wanting to spend. There are good shafts across a broad range of price points.
If you can give me a little information I should be able to give you a few options.
