In reply to Jason Hoffman: Well, I tried...there's a new tent from a small br...oh never mind.
What's your budget roughly? If I had money to burn and weight was a priority would definitely look hard at a Stephensons Warmlite. The 3R came out clearly on top in a recent Climbing review of expedition tents and it only weighs a touch over a kg. Would need the dams sewn in though. www.warmlite.com but watch out for the naked bearded types, it's the strangest gear manufacturers site I've seen in a while.
FWIW we have a quasar that's now 12 yrs old. That's quite durable! I didn't mind carrying the extra weight cos it's so strong. However within the last few years we've bought a Solar2 for UK backpacking trips and I'm very impressed with it's strength and weight. Bit of a pain climbing over the other person to get out in the night though. Reviewed repeatedly over at www.outdoorsmagic.com in the user reviews section.
www.antarctica.co.uk has the Southern Cross, on a similar theme, strong but heavier, much like the quasar.
Generally, www.robertsaunders.co.uk have lighter tents than the competition, and they're strong - at one time half the tents on the KIMM or LAMM would be made by them. My personal experience of them hasn't always been good, they're a little flimsy for the conditions I seem to have used them in, not that they've broken or the like but I just am spoiled by the Quasar strength and get edgy when poles invert in high winds.
Another one to look at is www.omegaoutdoor.co.uk/outdoor_tents_catalogue
who used to be phoenix, they had some good tents way back and they still make them. The Outpost I've had a few nights in and it was quite solid.
I'm really pointing these out as a few alternatives to the pack. I've never used MHW tents so can't comment on them (other than to say part of me has never quite got on with the whole window concept). Similarly, I've had bugger all experience of the swedish tents - hilleberg and haglofs, though reviews of the haglofs tents suggest that they're a little on the heavy side.
Happy hunting....
