JN, When you did the walk back did you use only field tips? Do you have a different rest to try? The reason I am asking is the I was having a problem tuning one of my bows(a Martin Firecat). I had a Ripcord rest (very similar to the Quad Pro). I switched out to a NAP Apache rest and the problem went away. What was happening is that I was getting erratic arrow flight no matter how I adjusted the rest. I can only assume that the Ripcord wasn't dropping out of the way fast enough for my arrow to clear.
