Personally I like the Brownell Braided serving, Ruddy (you've seen it on my strings). (I've also used the Halo but am not a big fan, though some folks love it.) The Braided comes only in Black and white but has three sizes - .018, .021, & .025. I use the .021 mostly but, when you can, it's nice to have all three on hand or at least the top two. I'll show you how to do a center serving (and an easy way to whip it off at the end) next time we get together. It's great to have a serving jig if you can but you can run the string from the spool through the center of a book (for tension) on the floor or table and do it by hand (jig is much easier and usually quicker). Oh, you can also "Double serve" it if your nocks are too loose (more stuff to go wrong though - LOL)
