I would totally agree with Arthur on the 3-strand Shurz. Never could shoot them well. Just when I thought I had myself trained to just ignore the little string in between me and the sight pin, I would catch a glare in the sun and it would be too tough not to see, LOL.
I have quit shooting peeps altogether. I put a small wrap of orange thread on my string that I can see as a blurry dot that I line up with the bottom of the pin guard. I try to put the fuzzy dot on the riser just to the right of the pin guard. My accuracy is just as good as when I used to shoot a peep under most conditions, and in low light, when a bright pin can make it very difficult to see the deer beyond it, especially through a peep, there is plenty of brightness left that the deer is still quite visible. Might be worth a try.
