Equipment can be a big part of it also. I have owned 4 jump sticks over the past 5 or 6 years, and some are definitely better than others. Now I am using a Predator Air, which jumps like a dream for me.
A couple years ago one of the vendors at a local tournament had a Dr Popper jumper for sale. I tried it on a practice table, and even though I am a fairly decent jumper, I could not even get the cue ball more than a half inch off the table with it. The vendor told me he had a lot of people trying that cue, and he saw a lot of times with that particular cue that people who had never tried to jump before could take that cue and use it with success, but people who had jump cues and used them effectively had trouble with that one. Kind of an interesting phenomenon. I did see that in the last trick shot competition on ESPN that Dr.Cue was using one of those sticks.
