RE: 4" or 5" vanes? helical or straight fletch???
I play around with both vanes and feathers, but I always seem to end up with feathers on my hunting arrows. 4" right helical. A moderate helical gives me good clearance, and stabilizes the arrow well. Feathers are a pain in many ways, but I have found nothing better for making broadheads fly!
