I dunno.....it SOUNDS good, that's for sure, but I'm not sure of it's validity. I'm not entirely sure the arrow leaves the bow any faster, the arrow just gets better energy transfer from the limbs and cams, making it fly faster. And, faster bows generally have a shorter brace height, so thestring travels farther to get tobrace, makingnull and void any gain in string speed. And besides, even if that is true, a fast arrow still is, and will always be, less forgiving than a slow arrow.
