Mauser06,

Get hold of Gibblet and have him make you a set of strings. This'll be one of the best things you add to a bow. First set he made me settled into the grooves in about 6 shots and have never changed. No creep and no peep rotation whatsoever.

Check out the G5 peep. If I'm not mistaken they make one with a 5/16" diameter hole. Just the ticket for hunting. Presently I'm using the Fletcher Magnum Hunter (1/4") but am taking a look at the G5 myself.
