yeah Talon, right wing feathers come from the right wing of the bird, etc. They curve a certain way, and the left wings curve the other way. If you use all right, or all left on your arrows, it really doesn't matter. Don't mix them.
Fletching jigs are generally oriented for one or the other, although there is some overlap allowable. Fletching clamps are generally right or left ( if helical). Again, don't matter which one, just use the right one for your feathers.
Single bevel broadheads spin too, especially when they go thru meat. If the feathers make the arrow spin one way, then the head makes it stop and start to spin the other way, it hinders penetration and makes no sense. Use the same "wing" on both feathers and broadheads if using single bevels.
