Both eyes open is a good plan. BD has it going on with shooting south paw to coincide with dominate eye. For those of you wondering how to figure out which eye is dominate. Simply put hands together making a small window to see thru, focus on a object in the distance and gradually move your hands from fully extended, slowly bringing towards your eyes. Never lose focus on object in distance. Whichever eye your hands end up in front of is your dominant eye.

Or just do the finger trick, works the same way. Line up a finger with an object, with both eyes open, then without moving said finger, close each eye one at a time, whichever eye shows the fingering NOT moving, is your dominant eye. That’s how they used to teach pilots in the Navy.
