RE: CB tuning VS bow tuning?
Not much you can do to tune the C bow. Should not loosen the limbs differentially, and changing the nocking point can't be done. Like Smoke says, about all you can do is play with arrow weight and string tension. I've found that arrows with lots of FOC (mine are over 20%) with small vanes and equally small, preferably four-bladed, broadheads gives me the best accuracy and consistent flight from arrow to arrow.
