I think i had some fun with those same Salmon on Sunday morning off Malabar. They were busting up everywhere but in a kayak it was hard work catching up. I was using a plastic slug type lure for a while then switched over to a metal after the plastics were falling apart. In terms of retrival, I would mix it up. If they were on the surface I'd try and cast past them and then rip it through the school quite fast, with a pause here and there. If i could see on the sounder they were down deep, I'd let it sink for 5 secs or so then the same type of retrival. Landed around 5, lost a few more. I also prefer single hooks as I don't often keep fish. Easier to remove and get straight back into the school.
