pointer, if you're going to encourage him to switch now would be the time. Don't think I heard of the eye dominance issue until I was in my 30's. Obviously it can be done when you're older but I think it would be a lot easier to switch as a child. It hasn't been an issue for me when bow hunting or rifle hunting. I do well on birds but skeet is where I feel a little handicapped.
He only shoots with the dominant eye now, both archery and firearms. I've had to basically quite shooting bows with him as I don't have a LH bow for him yet. This spring he'll get one!
