Welcome to the forums!

I use 1 pin, for several reasons. First, with today's newer bows shooting as flat as they do, the pin gap has closed in dramatically. Second, at least for me, I get really confused on what pin to use. Add those 2 together, and I'm all messed up. The pins are so close together it just looks like a big blob to me....Single pin sliders a VERY simple when you get the hang of it.
