In reply to john morrissey:
What about wild country foehn or hoolie 2?
The latter is a tunnel tent, so lots of space for the weight, however, I'm not so impressed with it's stability in strong winds, it gets fairly flappy, so if i was choosing again i would go for something with more internal structure.
800g difference for for the foehn vs, the zephros? is that a deal-breaker for touring?
