Buzzbombs from the beach at Sekiu are the cat's meow when the silvers are in thick. It is just like any other tool that can be misused.

Green/white, pink/white and black/white colors seem to work the best for me.

We just cast them out, let them sink for a few seconds, then reel in slowly. They will plane upwards in the water column if you reel too quickly, taking them out of the strike zone.
