I tried 4 fletch with my trad bows but not a compound.It worked fine but I still used helical.I think your best bet would be to use 4 offset if you're dead set on any type vanes and not willing to go helical or feathers.There seems to be a trend these days to use smaller fletching with less helical.IMO a big mistake.The arrow is 10x more important than the bow yet folks seem determined to sqeak by with as little as possible.That just doesn't make sense to me.I go the other way-3 5" full helical.
