Was wondering if anybody has used these - I know they are heavy and expensive but if they work in low light like they say I may be interested cause I have had some big deer get by me at low light. I was looking at the fly , it is an 1/8 inch opening and weighs 7.5 grains I believe. If I can get better accuracy with a smaller peep but still show daylight like a 3/16 or a 1/4 I'm going to. Just looking for opinions , Thanks guys.
