RE: Peep sight? Should I use one or not?
I've been using a peep for about all of my 33 years of shooting, both target, 3D and hunting. I use a larger one for hunting, usually about 1/4". At times I've practiced without one and can hold 3" groups out to 30 yards without a peep. I just have to adjust the sight some as I anchor differently without it.
A peep will definitely cut down on the amount of light getting to your eye, but as I get older I find that I don't hunt as late as I once did. When it gets dark enough that I can't tell a spike from a doe at 20 yards it's time to leave the tree, and I can still see my pins and usually the deer beyond it.
That being said, for about $5 I'd put one on the bow and try it if you haven't already. Give it some time for you to adjust to a new gadget. If ya like it then keep it. If not then take it off. It's really a simple decision.
