I practically never run assists that come with the jigs (unless I dont care about loosing a few fish during a really hot bite). Otherwise, I only run my own assists and terminal.

Used the sea rock to get the fish in the other photo, but after heaps of jigging after that and having none hit it on various retreives styles, I went with something that flutters more to try and entice them with a different action (pinged off first hookup using a similar SW labs one).

In that pic its a 1/0 (or 1, i forget) owner crane, to 9 split to 6.5 solid, ygk #25 braid, to SJ41-7/0. Attached using the way Kasey showed, then use low temperature heatshrink on the hook and the top knot held with a dab of superglue. I could probably upgrade the assist cord to something heavier for sambo jigging though (though its easily strong enough without the core, so the main benefits to a size up would be more leeway with abrasion?). Could have gone with a bigger hook, but didnt know the size of the fish, so went middleground. No problems with the setup so far (though owner hollow braid slips in the water if you dont glue it :S). It need a bit of tweaking to run during sambo season though. Any tips or suggestions?
