What size peep do you use? I have the small one. I am having a very hard time in low light, or in the woods period with. I find it hard to get a point of aim or reference point. I have had some friends say sure, its great for target shooting which I find to be true when shooting in the backyard etc...

1/4" G5 peep

Same here. Before I hit 40 I could use any old peep, made the change to this one and everything is clear again.

Yes, by all means go to a bigger peep for hunting. The better accuracy of a smaller peep is certainly outweighed by the need to see through it in hunting situations. Bigger might give up a little accuracy, but not enough to make much difference at normal hunting distances. Fletcher and G5 both make a 1/4" version. In fact, I know G5 has a 5/16" one, because I have one.

definately go as big as you can the bigger the hole the more light into your eye and also get a good fiber optic sight like copper john or spott hog that collects alot of light and is easy to see
