I can't commit myself to my drums... once I bounce, if I don't save the MIDI (oversight), I can't edit them any longer. Since I like to go back every couple years and redo the tunes with what I've learned, this doesn't work out well. Therefore, I leave the drums in Superior as MIDI, process them within the plugin (they've added cool and effective fx within), then again as a whole on the SD instrument track. That way, I can still process them individually and also as a whole.
So, I'll choose one of their compressors (usually the 1176 clone), throw it on the snare bus (toms, OH, kick etc) in SD, get a few dbs moving, then use another compressor (usually API2500) on the whole Superior track.
In Pro Tools, I can bounce the MIDI to audio, but still keep the midi track and just make it inactive. If afterwards an edit nags at me to do, I just make the MIDI track active again, do the edit, then just re-bounce over the previous one. This is usually just with VSTs (synths, piano, etc.) Superior I keep in the plugin also because I'm editing constantly (velocity, tweaking fills, etc.) but I do it a little differently than you. Check this out:
I route each drum to it's own aux track in Pro Tools, using the I/Os in SD and Pro Tools; the 3 kick mics to one aux track, the 3 snare mics to one aux track, then my toms group to one stereo aux track, the high hat to it's own aux track, the OHs to a stereo aux track, then whatever room I'm using to a stereo aux track (or track(s) if I'm using more than one room) Now they're always right in front of me on my ProTools mix screen, and I can use my plugins (Waves, Slate, etc.) on those individual tracks as I please. (If I want to just mess with, say, the kick "in" mic, I'll just do that in SD) Then, I route each of those aux tracks to a stereo bus to process the kit as a whole if needed. I usually just tap it (1 or 2 db's of GR) to glue the kit together some. Then I throw on tape saturation (Slate VTM), console emulations (Slate VCC)... Reverb I send to from the individual tracks.
Then I'll make another stereo aux for my parallel bus, and use sends from the individual drum tracks.
When all this is done, soloing just the SD instrument track brings silence, since they are all routed out.
Once you're ready to commit and bounce, you could one by one record them to an audio track. Time consuming sort of, but you'd be able to keep the MIDI file afterwards and just make it inactive. For example, if I was ready to commit, say I would start with the kick drum- I'd make a new Audio track, set it's "input" to an available bus, say bus 10, then route the kick track's "output" also to bus 10. Solo them both and hit record. Do this with each element of the kit, and you would have all you drum tracks as audio, but you would still have your SD MIDI track. If you need to edit, say, just a few snare hits, make the SD track active again, make your edit, then just re-bounce the snare track.
