I been practicing jumps shots lately ans i noticed my jumps are longer on my local pool room table then it is on my house table where i do most of my practice. I end up jumping over balls or throwing the cb outside the table in league matches. I was wondering which relation can be made between the slate, the felt and the actual jump of the cue ball. I am also using a non branded cueball at home, maybe the quality of the cue ball can makes a difference aswell???
