Brian,
I think you have it spot on, I think in terms of the elbow of the drawing arm being in alignment with the arrow. You can't help but have that energy flowing the right way then.
If the problem has not corrected itself, and you have a good tune, play with the brace height a little. Byron Ferguson said that he corrects lefts and rights once his bow is tuned by adjusting brace height. I have tried it, and darned if it hasn't worked everytime that the arrow was the right one and not too stiff or too weak.....Now that is good advice from the Master, I on the other hand is just a humble servant....
