Sabikis work ok...but they break easy, and you constantly lose hooks and rigs. I don't know if you can get them around here, but in the N. we use specially made mackerel rigs. Just like a sibiki but bigger hooks, a rubber colored tube over the hook shaft, and 30lb main line, been using the same rig for the last 6 trips now and they love em! The rigs come with three hooks, I just clip two rigs inline to make a nice stringer...
