Go the 9 wrap, 7 inch Alvey, 70-80lb Shnieder with a red rock crap and smashed up urchins for burley.
Wait till you see the Blue in the burley, get your fishing mate to get hold of you, drop the crab in front of him, and lock up on hook up. If you let go of the handle it will spin round and smash up your hands.
Getting these fish is a brutal battle. All over very quickly, one way or the other.
