I don't use the internal mixer of SD2.0. All the individual drum channels are routed to the individual outputs of the plugin (like Kick to 1/2, Snare to 3/4 and so forth) using the mixer page of SD2.0.
In PT, I setup a bunch of Aux tracks that receive these individual tracks from the plugin. There I do all the processing like sending the Snare to a reverb and stuff. From here on, I mix them just as I if I would have "real" recorded drum tracks.
Too many options kill creativity.
