Bear, I looked at the compound video (well, one of them, I guess it's the one you meant.) It was kinda black and white looking with the bow mounted in a holder/shooting machine. The danged thing on the string that they clip the release to went all the way forward and looked like it hit the rest! I counted about 30 oscillations in the string (both directions). No wonder they're so loud!
Hope I'm not out of line posting the above comment but really am doing it "in comparison" to trad. Never realized how much difference there was in the mechanics.
