I have a Quick tune drop away 2000 on my bow and started to have clearance problems. Well the bow shop says the spring in side it has gone bad and that I need to replace the rest. Thing is I need to do it quick and I wasent wanting to drop much money on it. He recommended a ripcord rest or the trophy ridge drop zone rest. My question is this. I wouldnt mind going with a whisker biscuit but how much is it going to kill me on speed?
