In reply to climber david:
The vango nemesis 300 is geodesic and outer pitch first.
its very large for two people, I haven't used it with 3 people yet but I think it would be comfortable.
It's 4.28 kg which is ok split between two people but you could get the two man version for a slight weight saveing (around 700g I think).
It's available online around £175.
