I personally use a 5/16 meta peep in conjuction with a two inch tru glo sight ring. It works very well for me in low light conditons. I agree 100 % with what Matt/Pa says. I still have good accuracy with the large peep shooting with both eyes open, even in near dark conditions. However, I do not shoot over 30 yards. Therefore I do not find it necessary to obstruct my sight window with too many pins.Ifthe lightconditions are that low you can't seehow to shoottoo far anyways.What works for one may not work for the other but it sure works for me.
