> "What does everyone think of the Hubba ...?"
Have some vicarious experience with the Hubba. When they first came out several years ago, bought one for a friend who needed something more reliable for heavy thunderstorms in New England. (We got wiped out on a high, exposed place called "Bulldozer Flats" on the Cohos Trail in NH, and had to waste an extra day just drying out). Have since made her a set a carbon poles that took off about 6 oz., and am working on a silnylon fly that will take off at least another 6 oz. Also, may make a pole set of Easton .344" O.D. poles that will still be several ounces lighter than the DAC featherweights that come with the tent, but stronger than the carbon. She has been very satisfied with the tent, and advises that it has been the one tent to keep her dry in storms, while providing good headroom. The biggest drawback is the floor width, 26", which would be too confining for me, especially with my 2 shelties, who are small, but do take up space. The length is not much over seven feet either, which can be confining for a six+ footer. With the modifications, the tent will be no heavier than the Fly Creek, and provide much more headroom. Unfortunately, the other Hubba, the HP is not much of an improvement in weight, with the window, and the addition of a partly DWR treated fabric interior to make it more weatherproof (The Hubba has an all netting inner). Note that in a gale, the Hubbas need secure side guys, as while freestanding, their design does not have a lot of lateral (side-to-side) stability. There are guy loops for this on the Hubba fly.
The Hubba is a great design, but it begs for a crossing front-to-back pole like the Akto or the new Tarptents, which would make it truly awesome. Only around seven additional feet of pole length would do it.
Hope this is helpful.
