Ok guys I've fletched arrows for 4 years and killed numerous deer with fixed blade broadheads out to 45 yds. All of the arrows I've ever fletched have been straight. This year my curiosity has gotten me involved in left and right helical fletching. I'm not sure which is best or to even go helical at all. I've heard several theory's by many trusted people I know. I don't know what to do honestly. Any opinions would be greatly appreciated
