RE: Left eyed, and right handed????
I'm left-eye dominant and shoot both bows andgunsright handed; for as long as I can remember, I've simply closed my left eye when aiming. It's worked pretty well for me... I'm no world-class shooter by any means, but I qualified expert with both a .45 and a 9mm while in MP school, as well as expert with the M-16... I've shot dragonflies out of mid-air with BB guns (yes, there was some luck involved) and am pretty decent with a bow...
Having said that, I just finished reading a column by G. Fred Asbell in The Traditional Bowhunter last month where he STRONGLY encouraged left-eye dominant people to shoot left-handed.
