I shoot a short (25") shaft and was having trouble with my thunderhead flight. I have had my tuning checked by a number of people and they said everything looked pretty good. I was told by one guy that having such a short shaft and using thunderheads that are a relatively long broadhead, compared to some other stubbier ones, that the blades on the broadhead might be catching too much wind for such a short arrow. Any truth to that? Would it be a good idea to try a stubbier BH? Anyone else shoot a short arrow and what BH do you use?
