I think a full suspension would cool to try out with drops. I've always had to go with an super short stem with a pretty àggressive rise to compensate for the long reach that road bars give to mtbs. My current dropbar mtb I'm using a 60mm stem and was a hardtail single speed 26er. I also run a 44mm wide bar for a little more leverage on the bumpy stuff then a 40mm I normally run in my road bikes. My dropbar mtb is one of my most comfy bikes but they take a little bit to get set up correctly.
