I have physically and mentally beat myself up on numerous occasions. Never blamed it on the bow. Just the operator. Most of the time it doesnt' get down to being the bows fault. It's the guy in the tree that didn't set up for the wind the right way or fumbles something, or has ant in his pants, or is caught with his pants down, etc............
My most shining moment was the all out brawl i got in with an oak tree. funny thing is that they dont' give very much and don't punch back either.
