yeah mate
that will more than cope, remember alot of fields have a cap on rates of fire,so even though a hopper may be capable of 20+ bps the legal limit is well below that, most high end hoppers nowadays are built to keep pace.
if that's what your going for then it should be fine, juts remember those are sound activated, so every time you fire, the sound causes it to feed a ball in.
I don't understand that? Sorry noob question. :/
How can sound feed a ball into the neck? :/
