are drop aways better than other styles? in theory? what about reality? how hard is it to set up/tune correctly to drop away in time? also with fast/light arrows? will it not drop away in time? and are the noisy? To me in theory they sound awesome, though mine current NAP quicktune works great, no problems ever, quiet. Heard of problems with drop away, though if they're set up right, are there still problems? noise? contact? more trouble than they're worth? Not broke? don't fix it?
