I have a spyder 2000 with a 32 degrees nyte stikk barrel.
Recommended Barrels:
small bore barrels work best. (lapco autospirit, nyte stikk etc...)
Strengths:
these paintballs are cheap money wise. They are very good from what i find. breaks on target and very accurate if used with the right barrel bore size. i have shot hoppers from 15 yards if that means anything
Weaknesses:
i cant find anything that is wrong with these.
Conclusion:
good REC paintballs. and again accuracy is based largely on barrel bore size. this is small bore paint.
