Good points Joel. I have wall bangers on my Oasis (command cams) and when they hit the stops it is firmer but still if I pull into it I get some " give" . I' ve never had a WC on my bow so am going on observations of others and some things I saw myself when looking at them. Several people have said they notice more noise from the bow after putting them on and along with hearing they are twisted up (like 1 twist/inch?) makes me believe that they are alot " tighter" and don' t absorb as much energy. That has to transfer to either go to the arrow or the bow. Just things I like to find out from others who know.
