Sounds like a god technique there Ben,I have caught them using unweighted Frogmouth with a slow sink and drop before, and also fresh gar fillets using the same slow retrieve.Long time between drinks for me with the Mullies though, just dont have the time and perserverance.When I did used to chase them, would be on the water every Friday night, sometimes more often,putting in lots of hours and getting in tune with the patterns, tides, moons, bait activity and so on.Results came with this, but I have found that now I just head down for a couple of hours here and there, basically no results
