RE: 1 eye or 2
OCD, i dont understand how you shoot the way you do, but if thats what works for you, then do what works is the way i believe! When TP is getting at me (it happens every once in a while) I always realize that i am not focusing on the target and am focusing on the pin. Like i said tho, if that makes your shots, then it sounds good to me...
I shoot with both eyes open 95% of the time, but there are times when i find it convenient to shoot with just one, weather it be b/c of glare or lighting condition or whatever. Idk when i noticed that i shoot with both eyes open, but its just what worked for me. I never really tried to do it, it just came naturally.
