I like fishing the ebb. I like the peace of mind I get knowing I can wade a mile or more without worrying about getting cut off by our turbo tides. Its true some places fish better on the flood, but equally there are places that feed well on the ebb.
I found one such place the other night, I waded out as far as I could on the ebb, down a sequence of gullies, and found a large almost lagoon thing that a few different gutters drained into - and there were fish everywhere, obviously waiting for any food coming down from the gutters. Its local conditions and environment that'll dictate whether its an ebb or flood mark, there's no set rule. It may even be both, fish holding in one spot on the flood, then shifting for the ebb.
That probably doesn't help you at all, so sorry about that!
