I shot short arrows with an overdraw when I shot compound. Those short arrows can easily change direction, or go off course. I think the craziest thing I noticed was shooting a deer quartering away at 15yds and hitting him in the bottom of the spine, dropping him right there. Somehow that short arrow entered right, but the tail end went down and the point went up and into the spine. I also wasnt as accurate at long distances with those short arrows. Now that I shoot trad, I leave all my shafts full length and tune by point weight. I draw 29.75", so Im not typically giving up much. Also it sure gets old seeing arrows on the classifieds that are cut to 26" or something short like that. Plus if you snap off a point, that arrow can be retapered and still clear your hand.
