Osage,
The conventional wisdom usually means right fletch, right wing, right-handed shooter. As a practical matter ya can shoot left fletch also, if ya pay attention to where the lower hen feather lays relative to the bow. You want the lower hen feather to pass right where the shelf meets the riser (or hand grips the bow) that means that the cock feather and upper hen feather will clear the bow. For hunting purposes, it's been my experience that if you choose the straight jig (and the fletcher allows for it) offset the fletch about 1 to 2 Degrees and you should be able to stabilize the broadhead. If the offset is left then set it up like the left helical hen feather. Just how it has worked out for me.... Now days, I do both ways ( but usually offset) so I can use more of the turkey feathers, they fly good.
