Franco: I really like the design of the X Rocket. I think it is my favorite tent design. It is too bad they don't make it in lighter materials (Cuben, Nanoseeum, etc.).
Looking at the X-Rocket reminds me of the "Tent-A-Palooza" that I attended at REI a little while ago. They had several models from the big tent makers (MSR, Bibler, North Face, etc.) with all sorts of tent pole designs. To their credit, they were fairly creative (although, again, nothing matching the X-Rocket for my tastes). The big drawback though, was that with the exception of the Bibler tents (which used a single walled breathable fabric) all of the materials were of, in my opinion, outdated, inferior fabric (no Silnylon, let alone Spectralite). It's too bad there is no place to have an ultralight Tent-A-Palooza -- except maybe at Franco's house :)
P.S. Sorry about the thread theft. I love reading this section, even if I make very little of my own stuff.
