RE: Arrows leaving nock high
Sorry guys, but I have to disagree. Normally an arrow flying nock high is an indication of too high a nocking point. It can also be an indication of too weak an arrow spine. (ref. Easton Tuning Guide) Since you are shooting with a release aid you may have affected the natural tiller of the bow. I'd try lowering your nocking point to below 90 degrees and see what affect this has.
