"Perfect form", as a statement, is not possible. "Your" form is dependent on your body characteristics, use of glasses or not, type of shooting you're trying to achieve, and fit of the equipment.

TFOX said: This is a very important criteria. If you are fitted properly, hunting from a treestand will be a lot easier. The four biggest problems a hunter has over a tournament shooter are; uneven and smaller footing, excessive or different clothing, shooting down (and sometimes up), and a target that moves. While 3D shooting may involve several of the criteria, it doesn't cover all the criteria.

Find a GOOD instructor that is 'in tune' with the variances.

good advice. I especially like bowfanatics!! Consistency is the key. Adopt a form and be true to it. I like to make comparisons to golf (actually I compare everything to golf). But, shooting a bow and golf are very similar. The shot routine is critical in golf. Pre shot, stance, alignment, grip, setup, ball position, etc.... have to be the same on every single shot. I know the # of breathes I take before I hit a shot.
Same applies with bowhuntin IMO. Be consistent in your approach and form will be a good key to success. Perfection?? Not attainable in either golf or bowhunting.

thanks guys.
