hey mate
ive picked up countless bonito around the area you are talking about running xrap 30's X2 and 1 popper just gotta keep an eye on your sounder some of the reefs shallow up fairly quickly 15m - 5m or so in not alot of time. i have also picked up a small tuna around the area one time, let us know how you go mate i think it looks like a pretty productive area but it's been hit and miss for my self.
