I just won a new custom Pronghorn takedown reflex deflex longbow, (boy is that a mouthful). I went and got some cheap carbons and fletched them with feathers. I put a nock point on the string at a 1/4" above zero. After shooting the bow some of the fletching is (leading edge) breaking off. Does nock point affect this or am I to expect this?

62" with 55# at 28" shooting a 29" arrow.
