a little followup:
I chatted w/ Ron and he thought the speedmid might be a better option for two, he also said he would be able to make a slightly larger inner tent to better take advantage of the larger speedmid.
I had pretty much given up on the duomid/duoinner, but made contact w/ a fellow member who is using this combo as a shelter for two (w/ his wife). It turns out we are close to the same height and while not overly roomy he's been very happy w/ the duomid. He does a use an inverted V pitch which helps w/ room- he also uses the mid guys which also make for a little more room as well.
I think I'm going to give that combo (duomid/duoinner) a go, if turns out too small for our needs I figure I can put it up on gearswap w/o too much of a hit and then go to plan B- supermid/custom inner.
