Sure. First, Shulz tells you to bend your arm on purpose. EVen though he himself keeps his arm pretty straight. It's best when your arm is straight but not locked. Second, he tells to use a firm grip- well, even Howard wrote to use just enough grip to keep the bow from flying out of your hand. Tight grips are bad, and lead to unecessary tension in your hand and arm. Lastly is the dead release. Beginner's shouldn't be told to keep their hand glued in place, because that can lead to collapsing of back tension. The truth is, he and Hill just
minimize their rearward movement as much as possible.
Again, all these things can be done and work beautifully (I mean, these guys are more than a little successful!) but the average person might be hindrered trying to recreate these tecniques (like me
).
