Many DXpedition organizers on oceanfronts speak highly of vertical dipoles or arrays of vertical dipoles for 40M/30M/20M. I'm not sure I've ever seen any of these have the advantage of a cliff to do something for 160M.
I myself have been experimenting with vertical moxons on 20M, the bottom of which is not much above ground level, including EZnec modeling, looking for a good west-facing antenna with well-defined TOA for domestic contesting.
