I am hoping len and some of the others that are in the bow business could answer some of these. Straightarrow I know that arrow building and tuning is your big thing, even your screen name says so.Personally I don't see the locking feature as a problem at all. I am one that usuallyfinds a draw weight that feels right on a particular bow and seldom changes it. I was hoping someone could tell me if maybe it would be quieter when shooting at a reduced draw weight somewhere in the middle of the weight range.
