Yeah, I know plenty of guys that can shoot lights out with what ever bow they pick up or show up with. They can hang with what ever bow they are shooting, and out shoot a lot of other guys I know that usually shoot the same bow.
Form is what its about, and form can transfer from bow to bow.
I once shot with a guy that showed me something about form. He shot while holding the bottom fade out just to prove his point. I could not believe how accurate he was shooting this way. Almost as good, I mean almost, as good as when his hand was in the grip.
