I have been reading this thread and really enjoy what you guys have posted thank you.I had problems paper tuning one of my bows tonight and finalylly found that I was using a slightly warped arrow and also wieghed my field tip just to rule out that varience.I also found that shooting from the position that I was shooting from would not allow a good paper tune.Also the other day a guy I know wanted me to install a shoot though rest on his oldie Fread Bear compound.After drilling and tapping the burger button hole and installing the rest then tryting to find center I found that there was no way that riser would allow that rest because of the cut out[:@]If he shoots feathers he may obtain fair arrow flight.Bill D>
