A friend of mine and myself were the first ones ever to use a phenolic tip on a jump and break cue...
You don`t have to do anything but chalk it if you like...When you jump a ball you shoulad have a proper angle, and that is aiming through 50% or half of the cue ball...
The breaking part of the answer is that you should make sure you hit with center ball...The phenolic tip works best with center ball...do not use anything but chalk...
Now I know there will be a lot of people "jumping " all over me that ...I we were the first ones to use it...There is all kind of proof,like for one a patent... It was a jump rod made of metal...And if anyone doubts me, ask Allen Hopkins who is a good friend of mine...
