I've shot aTribal (horrible), angels, Intimidator, Shocker, and I shot someone's Rain Maker once (don't even ask how much that gun sucked), Spyders with boo-ya/ESP (they chopped paint like chinese chefs)
AGD flatline 68cu 3kPSI
Several custom mods
I think that the only Necessary thing that you need to get to be tourney-ready is a new barrel.
The b2k2 is where it's at. I paintball as much as is humanly possible, and I've never had problems with it. The several different MOF (modes of fire) are great. I prefer the 3-shot burst <----It's nice because you can still use it as if it were in semi-mode, but when you get feeling lazy, you just hold down the trigger.
The adjustible trigger is about the best I've ever shot. Mine is shortened WAY down to just a 'tap,' probably less than 1/8 of an inch.
The only ball that I've EVER chopped in it was the very first one I shot through it--my boomstick wasn't on tight. Since then, never, ever, have I broken or chopped one sinlge ball.
ROF is awesome-who's gonna complain when they're effortlessly laying down 14 bps?
She's accurate. When I was testing my Boomy (and fav paint) with the gun, at 35-40 yards I was throwing a thight pattern; about six or seven inches in dia. I was VERY impressed. At 14 bps, there was no kick-back, it was very stable, allowing for great accuracy.
Nothing. Once you get your new barrel (I really like my boomy), you're set.
Perfect. For $650, there is no way you can go wrong. It's not just "the poor man's angel," it's the smarter man's angel.
