If u have the time, I've heard of a guy in Southern Ill. that goes by the name of Terry Wunderle. I read an article in F&S about him. He was a 2 time U.S. & World Champion Compound Bow Shooter. He now teaches bow hunters, pro-shop owners on that very subject, form. In fact, since reading the article, I've tried to follow the suggestions written in the article & have greatly improve since. Look him up if your serious about getting better. I heard the rate is about $250 for the weekend, w/other shooters. For personal lessons around $450, but don't take the prices for gospel. Just what I've heard.
