Regarding which wing(left or right)it will not matter, as long as you don't put both on the same arrow...lol
This is an old wives tale, from the old days. Some archer believed that having a arrow spinning away from the self or rest gave better flight.
Fact of the matter is that the flex, pardox, of the arrow actually has the arrow up and off the shelf by that time. Therefore it makes no difference. When I was in the service of our country, stationed in Florida. Most of the available feathers were right-wing. I move to Texas, and darn if it isn't left-wing.
So, I just purchased clamps for both left and right, for my bitz, multi, and grayling jigs. I have even had both types in the bow quiver. That brings up an interesting fact, at least for me, when I have both in my bow quiver, it allows me to have better spacing between feathers, thus reducing noise. Having said that, I am too lazy to work at that on purpose.
I hope this helps, you will find a number of threads on the site saying pretty much the same thing. Go with whatever you have, you just might want to purchase clamps of both flavors though.
