When I first read your post I was thinking along totally different lines from what Roseaukane and Paul responded with. True, a shorter draw length could potentially lead to greater accuracy because of the shorter power stroke but as Paul mentioned having the bow actually fit you correctly is of much greater importance.

Many folks will tell you that a slightly too short draw length is better than one slightly too long. I somewhat agree with that but would also counter with the point that the correct draw length is better than one slightly too short. Case in point, I have tried shooting bows a half inch and an inch shorter than my actual draw length and they give me fits. I end up putting too much torque into the grip because of having to bend my bow arm too much. This drastically affects my accuracy.

I would agree with Straightarrow...try to find a few Switchbacks with draw lengths close to yours and see how they feel.
