RE: eye dominance....major factor in shooting
I have always been left eye dominant and right handed. I play a lot of sports and its never caused much of a problem. How and why ? Your mind compensates - you just do it.
Shooting trad archery is an example. I do not, cannot, look down the shaft or use anything for any kind of aiming reference. Yet I shoot pretty good. How ? Its like shooting a basketball or throwing a baseball - just do it.
SO I've never cross dominance as an issue. Howard Hill was crossdominant, so is Larry Yien. When I shot a compound it actually made me concentrate MORE on looking through the peep with my non-dominant eye.
