Tying live bait rigs for halibut...

I want to tie up some rigs with a single hook that slides on the line above a treble hook stinger. I know how to tie on the treble, but how do I tie the single so that it slides easily like the store-bought live-bait rigs?
Thanks!

Google "sliding snell".

Good Luck.

Hey M2, I just tie mine like a steelhead loop knot and extend the tag to tie on the treble stinger. It doesn't slide but it's stronger. The slipping ones have been known to break from the friction of sliding under tension of a fish.
