If it works, it works. I've seen some pretty unorthodox "form" work, but rarely is it consistent.

The difference is taking the long, bumpy, off the beaten path, takes forever and a day scenic route........or driving straight there on a smooth, even highway. What coaches like Rod work to give us is the quickest route to the destination. Not to say you can't get there by other methods, but it may take 5 times as long.

IMO "instinctive" is way overrated, and way too often used as an excuse for lousy shooting. Even if you can be relatively accurate and not shoot the same shot twice, it's lousy for hunting. If you aren't shooting the same shot twice, then there's no way you can get good arrow flight every time. Good flight is essential to good penetration.

I'm much more impressed watching someone aim and hit the target consistently than I am with someone who says "I SHOOT INSTINCTIVE!" but sprays their shots all over.
