That sounds like its fine. What type of arrow are they? I cant tell by the spine if they're gold tips or Carbon Express. You have enough weight if thats what you're worried about. The only real concern is with that long of an arrow, the spine tends to weaken a little, but that still doesnt even to be a problem with what im seein. As long as theyre grouping right and tuning right, you dont have to worry about it.
