I'm still looking carefully at what tent to bring to the Alps this summer. Because of possible wintry conditions I want to get a storm-worthy and enclosed tent. Still I'm stuck between my Akto, a SilShelter that I modified with a TarpTent like pole in the back, my Gatewood Cape, my SpinnShelter, or possibly the Rainbow (though I doubt its ability to handle mountain storms). The Akto is perhaps too heavy, though a superb mountain tent. It also has a huge footprint. The SilShelter is what I'm leaning towards, but it is somewhat a pain to set up and the lack of a floor makes it dodgy on flooded mountain campsites, and condensation can be really bad. The pole and pole sleeve that I added on to the back portion of the shelter, where the SilShelter has had a lot of problems with sagging and unusable foot space, really helps to make the shelter more usable. The Gatewood Cape is what I'd like to bring because I can use it as a daytime shelter when taking lunch breaks, but I just have no experience with it in high mountain winds. The SpinnShelter is the lightest of the lot, but there has been talk of it tearing in high winds. Also when staked down in storm mode the headspace is so low that it is difficult to sit up and comfortably do things like cook or change clothes. The Rainbow is a great tent in many ways, but I'm not at all happy with the door system and am worried about how it performs in high winds. I'd prefer not to spend any more money on new shelters (or any other gear for that matter), but wonder if I should shell out for a good, fully-enclosed, freestanding mountain tent, like the MontBell Mighty Dome or the BD Highlight.
Any advice?
