I have to agree with Davidmil. Although not always the case a draw too long can really bum up a shoulder. My fatherinlaw's Matthew's Switchback "slipped" and the draw length increased to the point it fit me very well. It was out by an inch, and it was tearing up his shoulder to shoot it. The pro shop worked on it, found the problem and fixed it. Just a 1/2" too long of a draw on these newer bows can make a big difference.
