VQ:
Here's a recent video of the Duplex in a heavy rain storm on the A.T. (no connection to this person, just a blog I've followed sporadically). I don't know how tall he is, but you can get a good feel for the shelter. Just my opinion, but, for the PNW, I think I'd take the hit on weight for the extra room of the Duplex over the Solplex, especially at your height.

Mountain Shop usually has a few SMD shelters, but I'm not sure if they would have updated ones or if they would set them up. SMD is located off 217 in Beaverton and have been very accommodating to me in the past to come to both their old location (Ron's house) and their new one to pick up a few things. They might be able to show you a Skyscape or a cuben Deschutes tarp.
I've been trying to come up with one shelter system that is my go-to, that I know will work for varied PNW conditions and I've settled on a DuoMid and inner net (which I still need to buy). I'm in Portland if you want to meet up at a park and set up the DuoMid to see if the dimensions will work for you. I don't have an inner net for it yet.
