I use a Vango 350 something, tall enough to kneel upright in for the important stuff (as P2B notes), but also with an enclosed porch area to entertain during the wet intervals. Not quite as tall as Paul's, but also a bit lighter at 4 Kg. It was the shorter-section aluminium poles that made the difference in packing, compared to the previous tent's longer (but stronger) fibreglass ones.
So, how many know how to cross-lash-down a tent for stormy weather? (must admit, I've only ever had to do it once).
