Ya, with your C bow, the release is back farther (index finger knuckle under the ear lobe). If you draw your trad bow that far back, the arrow nock will move to the right causing left hits. It (the arrow nock) should be directly under your eye, not back on your cheek. Remember that you don't have the string peep sight on the trad bow for alignment. So you need to get the arrow under your eye, not beside it.
