Frankly, after a fair bit using a 2.5 pound solo biviy tent, and the 1-pound ID SilShelter, I've come to prefer the three-pound Hex-3, or Shangri-La 3, even for much, though not all, solo uses.

I like the extra space, and it's also good for two people. The Black Diamond Megamid is larger, lighter and cheaper, though I'm not sure it's absolutely better.

The Twin Peaks is a very good shelter, warmer in winter due to lesser volume, but it's a bit small with the two poles.
