Sounds a lot like a crab snaring setup. Fierce or a battle in 6000 or greater should do alright. I see a lot of them on Pacifica pier with 30lb mono. You might be able to get more distance with thinner braid. Max weight I’ve put on my ugly stick is 8 ounces for really rough conditions, but I usually use 5-6 ounces on a rod rated for 1-3. I’ve tried crab snaring with it, but it’s not really my kind of thing on piers,
