Rick,
as I stated in the clips, the swing draw is nothing more than a way to get the bow on target, albeit in a fluid, expedient manner. It is conducive for moving shots but works well for stationary shots as well....However, that said...
When shooting downhill (which we have alot of that out here) or out of a treestand, you actually don't swing at all, the swing turns into a more set-arm style out of necessity. If I'm in this situation or with many obstacles like limbs, etc. I put the bowarm almost straight out, then just move it a couple of inches into position as I'm pulling straight back the last few inches...this helps me keep everything fluid and not static like a true set-arm method.
