Yer your smaller rod should do the trick, I head down with the same sized rod and it serves me well.. caught me my first Frigate down there the other week! Lately there have been a few frigate swimming around Clifton... so look out for 'em! I take two rods, one to catch the smaller fish with like Yakkas, then another slightly bigger rod, which has a lure attached to it, waiting for the moment when the school of fish arrives and the surface of the water starts bubling with fat fish on it
Good Luck
