Hike in humid weather? Get a double wall and thank me later. Big Agnes and Tarptent are great brands (I own both brands). Freestanding is pointless unless you set up it up un-staked to see how level the ground is, then you could move it around to get the right feel when you lay. It also kind of cool to lift the tent up freestanding to "shake" stuff out of and off of the tent before breaking it down. Otherwise I have not been turned off by lack of free standing mode for my Tarptent.

Edit: It's worth noting that an adequate ventilated double wall tent will receive its fair share of condensation if you camp on wet grass in wet weather.I tested this at home one night... However, the trick is to have good amount of space between tarp and bug net so water does not run down the net to get your sleeping bag wet, or yourself! I camped on hard frozen soil, not grass, this past December and had ZERO condensation in my double wall tent. There's been nights I had no condensation, but my single walled friend had some moisture build up inside. Site selection is key, but in humid weather I'd take a well ventilated double wall shelter any day. Hike your own hike!
