my brother and i have just returned from our weekly, world class (we think) round of woodsball,and have combat tested my new barrel.we played something like 5 games,with fluctuating teams of 8 to 10 guys. i play with an A-5 with flatline,but have decided to try accuracy over distance,after seeing how happy my brother has been after switching from his flatline to a J&J ceramic he had lying around. i used a 14" CP one-piece i just scammed cheap from paintballoutlet,and couldn't be happier !! i'm recommending this to a couple freinds in the market for a new barrel,and one guy,after seeing it in action,said he's getting one this week.
