The rig you refer to describes our Topfloat Strayliner.
There’s our Topfloat Surf Boss too that would work well over there despite the absence of surf.
The Surf Boss is actually not much cop in turbulent water so the sounds would be perfect. Ideally, use a stone sinker on a rubber band or similar so snags stay with snags.
Re the closing comment on hooks, I think the previous report for Sean’s Marlin on 6/0 Youvella sums that up pretty well.
