Good point, Terry, there IS much to be learned/considered in the shooting methods. Howard Hill once told his students to make up their minds what they wanted to do, hunt or target shoot, because the two approaches don't mix well. I tend to agree with that logic. I don't think he meant it as a slam on either style and I certainly don't. In HH's case its simply the perspective of a respected individual very experienced and accomplished in BOTH arenas. There's much to be said, and learned, from that idea.
One MIGHT even consider the hunting style (canting, instinctive, simple gear, absence of accessories, etc.) as the 'traditional' style since it started with the first bow and the first bowhunter, and the target style as something more specialized that evolved in pursuit of more accuracy with the bow and arrow. Nothing WRONG with either approach, they are just DIFFERENT approaches.
Sometimes we confuse/meld the two styles and end up fighting over the differences.
