This is my opinion. There is only one jump cue, RAT.
I got one about 3 years ago and it WAS the best i've ever tried. I've played with them all, Predator, Stealth, JJ, Lacosi, .
I must say i liked the 3 piece jump theory so much that i called Ryan RAT cues and had him build me a one of a kind 3 piece jump cue and it is without a doubt the best jump cue i've ever used. I love it when i'm at the pool room or at the bar for league night and people start talking about their jump cues. I pull mine out of the bad and let everyone try it, all agree, the best.
BUT, you pay for what you get. The jumper wasn't cheap. But i got the cash and i knew Ryan would build me a jumpn beast.
Thanks Ryan!
