I owned one for awhile and even though I kind of liked the tip, the overall cue itself was ok at best. I have a BKII and would use that any day over the Icebreaker. The only benefit I see is being able to break it down to two different jump cue sizes but who really needs that when you can buy a $50 jump break cue that is decent IMO.
I broke 2 Predator break shafts last year. Do not like the Predator break cue at all.
Anyway, that is the reason why there are so many choices out there.
