I recently ordered a mildly customized cuben PyraTent with fixed vestibule, plus single PyraNet with cuben floor and 10" walls, and made-up pole from John at BearPaw Wilderness Designs.
The service was impeccable. I received rapid and helpful responses to email requests, John took an (unavoidable) lengthy international phone call at night, and easily surpassed my tight deadline.
The PyraTent has almost a hand-hewn appearance that I rather like, rather than being a machine product. I had not experienced cuben before (here in Korea), but it seems to be a material that one can get close to, and not feel uncomfortable.
I haven't had the opportunity to test the tent in the wild yet - but very soon.
