Another one with a box walker . . . on straw. I really find that the deeper the bed (and the more established it is), the cleaner he is. I do a total muck out daily - lift the whole bed - but put the "dirty" (as in the stuff that I have left after I have removed all the poo and wet) straw on the bottom - at least 10 inches deep and then top up with clean. I find clean straw skitters about too much, but the more mature stuff makes a more stable bed that, once it's deep and heavy enough, hardly moves.
I have experimented with all sorts of bedding - shavings, bedmax, littlemax, flax, aubiose, etc. and, managed right, nothing is as effective or stable as straw.
