Cool link on the sea bass. Looks like you don't even need rigs. You can just order sea bass on Amazon Prime!. lol.
Kidding aside, me and my dad use a 30-40lb test leader. Dad likes Ande Monofilament, I seem to have luck with fluorocarbon... 2-3 foot leader. Surgeons or slip knot on the bottom for your sinker. 1 or 2 dropper loops 6-8" apart. Then short a snelled hook attached to the dropper loop or loops. I have even just set the hooks right on the dropper loops as well. Deep water we do Hi/Lo and shallower just a single hook. That is just how me and my dad do it so... I will get you some pictures tomorrow night. All my gear is on the boat right now. I am interested to hear what other guys do.

Simple hi lo rig with 24" leaders of 30# or so 8 to 10" apart and a 12 or 15# 6" leader for the sinker so it breaks off on snags is what I use. Of course half the sea bass I catch are while fluking jigging bucktails.
What I use is good for sea bass and fluke. 2 - 3 foot 40 lb leader with one drop. Swivel on top and snap on bottom for easy changes. # 5 hook with UV hair for the drop. For the bottom, instead of a sinker, I use 2 and 3 oz jig with UV hair so I can change them depending on conditions. I've had better luck with Big Gulp jellies than with squid.
The jigs usually need hook replacement. To do that I cut off the large hooks jigs usually come with leaving some of the shank. I then tie a swivel onto the shank using thread and 1 minute JB Weld.
It takes some time but makes for a great winter project.
