Center serving a two lined flemish twist

[Maryland Mountain Man]

Makes sense!  Thanks for the replies.  I've got a Modoc, Mohawk, Penobscot, and an English longbow that I'll be doing with this.  Ordered one of those BCY serving tools to hopefully make it a much quicker process and I already had a spool of .20 Brownell Trad-X I'll be using.  This should have two benefits for me.  I usually heat up my nocks and spread them to get rid of any drag from the nock and with these smaller diameter bowstrings this will no longer be an issue.  The Easton H nocks on my Beman Centershot arrows eventually pull back toward their original size and I end up separating them again.  You guys are awesome!  Thanks again.
