Shoots striaght and quick, with some handshock, but quite accurately. It outshot my friends Bear Montanna with a similiar gpp arrow ratio.
Arrow tuning is a bit of a pain, and I prefer them stiff in the center to lessen handshock, but for the most part they're reliable hunting bows as I see it. And Manny's post sure shows that
