I think that a lot of y'all who are shooting with one eye closed are putting WAY too much emphasis on "aiming". You aim when you are shooting with a scope at indoor spots using clarifyers and all that trash (well its not trash but you know what I'm getting at).

I shoot both eyes open. Always have. All my focus and concentration is on exactly what I want to hit. I notice the pin... and sure its a little fuzzy... I have 20/15 perfect fighter pilot eyes too. I focus on my target, notice the pin... and before the arrow is gone I can see the nock going right to where I want it... then there is a woosh.

Nobody is dead rock steady.... just cannot happen... you focus on that one small spot and make a good shot and its going to happen.

For hunting... you should absolutely be shooting both open... folks who complain about not being able to see through their peeps are near always shooting one closed. If you are left eye dominant... you should be shooting left handed.
