Vanes can be fletched in any configuration that you wish. There is no right of left wing for vanes.

Feathers are called right and left wing due to the way that they are cut. They will bend around the arrow shaft in one direction only. Next time you are at your pro shop look at a right and left wing feather side by side. Notice the quill of the feather and the side that it is cut. On a right wing feather the quill will be on the left side of the feather (looking from back to front) and opposite for a left wing feather.

I also agree with the rest. I like right wing helical with feathers. But it is a complete personal preference with a compound bow. It does make a difference when shooting a recurve or long bow off the shelf.
