Thanks to all who replyed. It was definatly the tru nok. I removed it and just went with a single brass nock and bingo a small tear low, this brought a huge smile to my face as I new I could work with this, a turn and a half up with the nock and YATZEE! It was in the back of my mind I was just to stubern to remove a 15 dollar nock set.Sometimes the truth just sucks. Well at least I'm still married [&o].As far as my center shot set up all I've ever done is just eyeball it down the middle and line the arrow up with the string to get close and let the paper do the rest. Well gotta go sight in a bow got a 3-D shoot next weakend. Anybody looking for a tru-nok I know where you can get one cheap! Thanks Again.
