You can still do shavings, even if you don't do deep litter. I have a very thin layer of shavings (on top of sheet vinyl). I do have a poop board, so very rarely do I need to clean poop off the floor. I will say that I put some crumbled up smoker pellets (that got wet) onto the poop board, they basically turned to sawdust and are very dusty when sifting the poop board. That said, if you leave poop on the pellets, the moisture may start to break them down to dust. I don't think you will experience any real difference in temp, by using pellets vs. shavings, if that is what you are asking about.
