the benefits of carbon over anything else as a seatpost material are vanishingly small. Get a Thomson; they don't break easily and hold your saddle where you want it.
Each to their own. I've got a layback on my S6 and I don't think it's half as bad as everyone makes out. How much post below the bend you've got makes a difference too.
Better than the current Zipp seatposts that kind of melt into a tangle of weird, gloss angles.
