I use the Egg Beater Mallet C's, which work the same way as the ATAC Z's. Both pedals are nice because you can use them as either platform or clipless. The "clip" mechanism in both work well in snow, mud and ice. I really like using clipless in the winter because of the extra control afforded by being attached to the bike. Rarely, I wont be able to clip out in time, but I think the benefits outweigh the risks.
