Say a clamp breaks it is an odd proprietary clamp as well so you could be well screwed if something does happen. Granted yes it is not often these things happen but they do happen and that is why proprietary seatposts don't do it for me. A 27.2, 30.9, 31.6 seatpost is really all we need simple round made by most all the manufacturers of seatposts in at least one of those sizes and sometimes most or all in such a wide variety of options.
