SG I have a few of bob lee' s redwing hunters . Great bows very easy to tune and fore giving to shoot. If it's a RW hunter made by bob it likes a real high brace hight of anywhere from 8" to 9.5". If it is AMF or head Ski it can be as low as 6" to 7.5". Use a B-50 Flemish and not a fast flight string unless the tips have been re enforced. If it is a bob lee bow you can look him up on the web ( bob lee archery) he has a shop in Texas and he still answers the phone and will help you out.
