Tippmann A-5 with a Dye Boomstick.... It's all i need.
i used almost every kind, All-stars, Evil, el tigre, kick'n, etc... i never had any problem.
it is very accurate, and actually quieter than a whisper.
i wish it was all black... the silver gives you away sometimes in the woods.
This is my most favorite barrel i have ever used, very easy to clean, very accurate, and quiet. And you can buy diffrent middle pieces to adjust the length... All in all a very good barrell. i'd reccomend buying this over a boomstick for the price. Even though ive never seen a pro use this barrell it is still very good. it is very nice looking, and comes apart in 3 pieces so it is easy to store in a small place. I have shot many diffrent kinds of paint out of this barrell, anything from Diablo's to the cheapest stuff, and i've never had a problem. Maybe that is due to the way the A-5 shoots. I dunno, but i highly reccomend this barrell.
I'd reccoment this barrell to anyone as a serious upgrade from stock... and a good upgrade up from almost ay other barrell... i'm only gonna give it a 9 though because i wish it was all black.
