I was at my local pool room yesterday talking with a guy that I respect for his pool knowledge. He was saying he did not like playing with Predator shafts. I am trying to figure out why. I have been playing with a Predator for the past year and playing much better. When I got home last night, I started playing with one of the shafts that was made for my cue. I couldn't make a freaking ball. I was ready to turn in for the night, but decided to put the Predator back on and started playing much better. What is the difference between these shafts? Any help understanding would be appreciated.
