Does anybody else have trouble keeping their Bodoodle rest tuned? I have a Bodoodle Pro and the speed fins seem to constantly change. I have moleskin on them and it seems as the moleskin wears, the rest changes which only seems logical. But it also seems the speed fins are flimsy and either bend or ?. Also, what purpose does the side fin serve? It's the only rest I've ever used but thinking of going to a WB. I love shooting but really only do it for fun or hunting, no tourn's or anything.
