Thanks Don.
The lost and be found technique:
You also could toss a flasher and retrieve it constantly. That technque produces relative rates of success. The downside is you may lose the flasher frequently. Is all about rythm and timing.
The "Scumbag technique"::D
The combination of a chumbag (dive net bag full o stinky crap) and some flasher is another story, just drift along the chum cloud and let the flashers fly nearby..
