I have some issues with the soloplex, but one thing that was great was that I never really worried about setting up in the rain-the cuben fiber material dries really quickly so if I set it up in a downpour I could just use my t shirt to dry off the inside of the tent and it would be all set within a few minutes. I set up in downpours quite a bit, especially in Maine.
What I don't like about the soloplex is that water would pool around the tent and subsequent rain drops would hit the puddles and "hop" over the bathtub setting and soak the insides of my tent. This was really only an issue in torrential downpours, but Zpacks needs to address this problem quickly.
Also, I recommend paying and extra 50-60 bucks and getting the duplex tent from Zpacks. It weighs maybe 2-3 ounces more and is really more fitting for one person. I had a hard time fitting all my gear into my tent each night.
