A "relaxed hand" with a deep hook. Relaxed hand and weist. It sounds od, but it helps eliminate torque and promotes a clean rearward, pullng releasein line with the line of he elbow through the arrow.
I read about it on the threads here, and tried it by getting a deep hook witht eh finders, and consciously letting my drawing hand and wrist br loos, even wobble it like a loose rope attaching my hooked fingers to the strng. The result is pulling straight, as the draw pressure pulls your relaxed hand and weist straight, 'caue it's loose - relaxed. Arrows go straight.
Now, with that relaxed hand and wrist, a comfortable angle of the hand on the string won't hurt (induce any torque), as long as the hand and wrist stays relaxed through the draw and release.
maybe hat's it.
