John Schulz produced a video quite a few years ago that shows how to do the swing draw that Howard Hill used. But that wasn't the only way Hill drew the bow. If you watch videos of some of his faster shooting, he is using a push pull method, which is what Fred Bear also used. I use all three, depending on the situation. If I'm stump shooting, swing arm seems to come naturally. Drawing on an animal, I usually have my arm extended toward the critter before I draw. Then, there's very little movement when I draw. On small, mobile critters like rabbits and squireels, I may use swing arm or push pull, depending on where my bow and arrow happen to be when I see the critter. For 3-D shooting, I tend to use push/pull almost exclusively. They all work, and I like to practice all three.
