Karnage Tear, Proball, X Ball Bronze, Bonus Ball, just about every other paint out.
Variety of markers, primarily a SP Ion Fully Upped with freak barrel
I used a .687 insert.
Consistency in shape and how it shoots. Extremely round.
None so far, color options maybe?
Not one broken ball in 10 different guns, shoots excellent. Nice fills. Not a top level ball as the fill isn't designed for high level tournament use. I'm super impressed with the quality of this ball, in fact I haven't seen much better lately. There are plenty of options for good paint these days, this one is another quality paint that I recommend highly.
Try it! I'm thinking the other reviewer had some bad paint that wasn't stored properly.
