Greg, I missed reading this post until now. Very nice job and great pictures. I've always tied my string nocks with overhand knots - two layers thick. I like the looks of your method of serving them. I'm going to give that a try on my next one. Just one question - how easy are they to twist up and down the string to make adjustments? Do they stay together well if you have to make several adjustments?

The difference in mine - I always make a catfish loop - they don't stretch and are ideal when using string nocks and I leave about 1/8" gap between nocks (with arrow nocked) to help prevent pinch. Maybe I'll make it a point to do a pictorial of mine so people who've never tied one, can see how to tie the catfish loop.
