http://www.robinhoodvideos.com/ i woudl say that it is probably one of the best videos on form ever i learned a ton from this man in just the few minuts i talked to him at the IBO worlds but i would highly recomend buying the video, it is worth every cent and it will improve your shooting greatly but i must worn you be prepared to shorten your draw length[
