Best I can measure from centreline of limbs to arrow plate is about 7/16″ – certainly not past centre. The bow is a Robertson “Mystical” Stykbow. I’m not sure if that’s considered high performance. I’ve ordered dacron strings from Robertson but I but I have no idea what grade of dacron they will be. I’m trying to stay away from “fastflight” strings because I have no familiarity with that material.
