Vaude Power Lizard has very large amount of usable floor space. I'm ~6'2" and I can comfortably sleep in it with my rucksack and various other things at my feet (not under). Can't find official dimensions on Vaude site but from another site it says inner floor is 228cm long and I can believe that. Mini-poles at either end mean it's all usable. That said if the flapping from a Terra Nova Laser bothers you then you're likely to have the same problem with this.
Orange self-inflating thing (can't remember name!) that I now find far too uncomfortable and it kept getting punctured somehow.
Neo-air which I like but I'm terrified it'll get a puncture and it would be nicer if it was wider (I got it just before the mummy shaped ones came out which is a little annoying).
Z-lite folding CCF thing which I got on a whim as a possibility to combine with Neo-air to protect against punctures even though I can't see mysefl carrying both. Surprisingly comfortable though so may use on it's own sometimes if I can work out a decent way to strap it onto my rucksack.
I tried out some Montane Terra Pack Pants over the weekend. Exceptionally light and after getting wet seemed to dry almost instantly. Can probably get similar for less money but I was really impressed.
