jag,
You can get the peep set up so you can see between the three strands, it just takes some time and patience. The " two strand" model is called a " Shurz-A-Peep 2X2" and it has two notches on each side of the peep. Regardless of the one that you use, be sure that you have an equal number of strands in each groove, so that it will rotate consistantly to the same point, if it does rotate.

I hope this is what you' re looking for.
