here is one for the medium size mullets....
Make your trace already, sinker mainline everything except the hook. Make the hook trace a little shorter than the sinker trace.
take a bait needle, and thread your trace (.80 for me), under the skin of the mullet next to the spine from just before the tail to just behind the head. Pull almost the whole trace through, and leave the sinker mullet and all the rest in your baitbucket, rockpool, whatever u using for livies so it can chill while you tie on the treble hook.
Now i think it's vmc, but there is a treble called a "scorpion", with 2 trebles 1 size, and the 3rd one 2 sizes bigger. This works the best but a larger treble will work as well. Pull the trace back so the 2 legs of the treble is on either side of the livey, and the larger treble is standing upright on it's head.
Now you have a livey that you can "clip" onto your grapnel and cast like you would any other bait you need to get out further.
