RE: Bad cam?
Sorry to hear that. If you have any doubts you can express them on his feedback. Maybe not a slamolla feedback, but one stating the facts as you know them.
At this point in the game I don't see myself ever buying a BT or Mathews used w/out the warranty. Unless it was such a bargain it wouldn't matter (like my $114.00 shipped AT Stalker[8D])
I hope it's robin hoods and xXs from here on out. If you were considering a draw length adjustment, now is the time to do it.
