Fast to me is considered anything over 310fps... that is for fast in general.

Fast for hunting, with hunt ready arrows and broadheads is anything at or over 275. Smokin' fast is over 300fps. You just don't need that much speed with a hunting set up... gets harder and harder to shoot well with it.

My bow is throwing 454gr arrows at 282.... to me, that is about a perfect balance of good fast speed that is controlable, with a nice heavy arrow that carries itself well.
