For you guys or gals shooting self bows, which do you shoot.  Right or Left wing.  Or have you found and difference between the two?

Makes no difference unless you plan on shooting single bevel broadheads like Grizzly or Abowyer.

According to Dr. Ashby's penetration testing, Grizzlies match to right wing and Abowyers match to left wing.

Makes no difference. I'm right handed and shoot left wing, my brother is left handed and shoots right wing. I know that's old school, but we get to use both sides of the bird that way so it all works out  

I use both. As long as you use the same side on each arrow they will shoot fine.   Pat

I thought it was right wing in the northern hemisphere, left wing in the southern hemisphere.

I'm with Pat B. I have some of each (I'm right handed) and as long as I do my thing right, any of them will do there thing right. Just don't ever mix 'em by accident on the same arra or they'll drive you nuts before you even get to the shooting stage - trust me! ("What the blankety-blank devil is going on here with these fletchings???")  :D

I am right handed. My last osage bow did not like right wing feathers. I can't explain it either. Usually what youu shoot doesn't matter. Jawge
