In Eye Off...you can set it to whatever you like, almost. Upwards of 30 CPS...however, you do need to feed it at this speed, or it will chop...you are better off with Eye on, and a fast loader, like a Halo B, V35 Halo, or Z board eggy.
Eye off is great for dry practice, much fun...but, have your Eye off set at something that you can rely on, should the eye fail in game...you dont want to outshoot your hopper!! Say 10/12 Bps/
