I like the same set up as Mili, pulley rigs are good at stopping them rolling up and busting off. I think fresh or fresh frozen crab is the best bait, half or whole. You’re Solaris will handle casting whole crabs easy if you use an appropriate sized sinker (I like 4oz).
It pays to keep your rods wide apart when targeting biggies, rig over 15kg can easily tangle you up, been burnt a few times with lines crossing. It also helps to have a strong shockleader for handling them in close around the drop off (abrasion).
Be prepared to fish late into the night and have a good headlamp, it makes landing them alot easier!!
