I actually bought 2 12.4 predator revo shafts and 2 classico predator cues. My plan now is to use the predator victory soft tip on my playing cue and the Zan hard (original) on my break cue.
Well I sorta stole your plan & got myself a 2nd revo 12.4mm with the sport 2 black butt w/sport grip & Samsara b/j Tip to become my new break cue. Really wanted the ice version of the sport 2 but I'm impatient & didn't want to wait for them to get more in stock & with my luck when they did the shaft wouldn't be available.
