Downhill decks are built for stability and speed. The innovation in deck features that have come out of this discipline in the last decade are unparalleled. You can ride a top mount, drop thru, drop deck, double drop, micro drop. There is W concave to get your tuck all tight and comfy, there's bacon concave to get your feet placed just right. There are so many more...  A couple of decks we dig for the downhill discipline this second are Loaded's Truncated Tesseract  and  Rayne's Fortune
