Tim,
I'm right eye dominant. I can shoot both right & left handed, but am a much better shot as a lefty......99% of my shooting is left handed.
I've always shot split fingers with acceptable results hunting. I learned years ago that I can't compete with the 3 under shooters. Being cross eye dominant proly doesn't have much to do with that fact....LOL
Shooting bows is the one and only thing I am able to left handed.
