I plan on owning one in the near future

. But I went on a week long trip out to Bandelier NM with two other guys. One has the Cloudburst (tube design) and the other had the squall (modified a-frame). The Cloudburst had the floor sewn in to it - it is spacious and has a few more options than the Squall. The Squall is the one I will get though - much lighter. I use trekking poles, so that is an easy way to save some ounces because the squall can set up with a trekking pole instead of an extra pole (weight).
Alot of the guys I backpack with have one of the two and speak very proudly of them.
