I've been an advocate of straight fletch for years. Well, when I went to a little faster setup with lighter arrows I had to work harder to get broadheads tuned. I'd start with a dozen arrows and end up with anywhere from 6-8 that I called hunters. I'm picky. If it doesn't shoot like a field point I don't use it. The last couple times I had arrows fletched I put in a little helical. Not much, just a little. It sure has helped my arrow flight.
