I ues a Triball BBT 2.2, on it I have a Dye Excell, AirAmerica Raptor Rex 4500psi system, and new anodizing.
Strengths:
Its can feed 16 balls a sec. even on turbo 13 balls a sec. it feeds constanly with not a single hault of operation. I had a full hopper and shot it non-stop on turbo 13 balls a sec. 300fps no balls chopped and feed constantly. It also turns off automaticaly when your out of balls, cool multi color LED ,and button no dip switch. Its alos super easy to install!

nothing at all!
Conclusion:
For price, its a necessary upgrade for super fast guns, it'll keep up with any ROF. Get one!
