The Laser competition is unbeatable for size & comfort for 1 man (although sometimes with the door shut I feel like I am in a coffin lol) I have tried the Akto, which was alright, but definately not worth the extra weight or money..
For a 2 man I have a robens mythos duo, which is also great. I wouldnt camp on a ridge a KM up in it like I would in the laser competition, as the stability system isn't quite as good. I fear I would spend the night holding my tent down in the wind instead of sleeping
Great for glens or corries though...
A 2 man tent really does weigh twice as much, so I would invest in two tents if I were you..
