I have 17# triple fish on my spools. I use two different type of weights depending on the purpose of that rig. For poles that I use for plainer boards and bottom fishing, I use the rubber core weights. That way I can change out or go with no weight at all without re-rigging. For down rods that I also use for bottom fishing, I use 2 or 3 oz egg sinkers. Otherwise, the rigs are the same.

If it's an egg sinker, that goes on first. I then attach a swivel and a 2-3 ft leader of 17# fluorocarbon. I like this because it has a break strength that is lighter than the triplefish so if it gets hung, I can get my weight back. Then I'll add the hook. I use either circles, owner bait, or even treble hooks. Lots of people use the octopus hooks and they work great too. The hook size should be determined more by the bait size than anything. I typically go with a 2/0-4/0 but can drop down to a 1/0 or even a #1 if the bait is smaller. So it ends up looking just like a Carolina rig only it has a bait hook instead of a worm hook. If its a "rubber core" rig I'll add a 1 oz weight above the swivel.

And for those wondering, the rubber core weights do great for me, even bottom fishing. I can use a rig pulling boards with a 1/4 oz, then switch to a 1 oz bottom rig with the twist of the rubber.
