pmi super swirl, wild stripe, zap-the cheap ones, other walmart balls.
ion pro with freak jr. barrel viewloader evolution 2 with y-board, 48/3000 psi pmi nitro.
Cheap, shoot pretty straight, don't break in barrel.
Hardly ever break on people.
I bought these balls from my local walmart for around $30. For $30 they are a pretty good deal, they shoot decently straight and are pretty cool looking. However they hardly ever break on opponents. I have had people tell me I shot them but the paintball didn't break. These are good for messing around with friends or for target practice. But they are not good on the field.
don't buy these unless you are trying to save money or if you are messing around with friends. If you are playing for real buy some x-balls for ten more dollars.
