Those catches are amazing.
I've hooked some large ones of the rocks in Lombok but always cutoff
.
Like you say they like it coming into shallow water, most of the hook ups I've had are right on the ledge eyeballing the fish, and the fish after hook-up, running parallel along the edge with subsequently fast bust-offs.
How long and what type of leader are you using?
My hat's off to you bud, respect.
