I am not the halibut killer that others are on this site, but when
I am...
I like to use the black Danielson sliding sinker rig with a bead
between it and the leader knot.
When tying the sinker leader I use line that is about one
half the strength of my main line/leader so if it snags
the bottom I can easily break free just losing a sinker.
Having said that I have yet to snag the bottom with this rig.
