Try a Easton XX75 2216'swith a 100 grain broad head(get some 100 grain field tips to practice with) My brother shoots a older Browning bowand thats what he uses.
Seems to be pretty quiet.(now if I could just get him to change his vanes to
Quick Spins!)
Also, you might want to try adding some LimbSavers for the limbs on your bow.
