This occurs because the shorter the bow length, the more the bowstring wraps around the drawing fingers. The more the bowstring digs into your fingers, the less likely your release will be smooth and accurate. Another factor in choosing bow length is maneuverability. If you hunt out of tree stands or heavy cover, a short bow can provide an advantage that the cumbersome long bows cannot. There are also the issues of speed and accuracy.
Shorter bows shoot at high speeds, but tend to be less accurate than the slower long bows.
Overdraws Overdraws are another area where your shooting style dictates need. The release shooter will find that an overdraw rest will allow them to shoot a shorter and lighter arrow, therefore increasing speed and accuracy. While this is an advantage, don t get too carried away. Long overdraws will amplify mistakes in bow holding techniques. If you are a finger release bowhunter, stay away from overdraws.
