I have a Nap Quiktune 1000 shoot through, prong style arrow rest. I have heat shrink tubing on each prong to silence the arrow when drawing the bow. I have noticed that the shrink tubing on the right prong gets almost 100% of the wear. In fact, I almost never have to replace the tubing on the left prong, but have to replace the tubing on the right prong every 50-100 shots.

What could be causing this? Shouldn' t the heat shrink tubing wear equally on both the left and right prong? Could this be due to torquing the bow? Could my centershot be too far right or left? Could this simply be the way my Mathews Q2 shoots? If I can manage to get a near perfect bullet hole in paper tuning should this be something I need to worry about or should I just keep replacing the right prong silencer?
