Dunno which the Arran 5 is but on the whole i find em a pain in the butt.
Compared to your quasar the only possible advantage i can see is that you can have a (controlled) fire in it, solong as you have some ventilation to avoid carbon monoxide poisoning (Iam serious).
Other than that i really can't see what the fuss is. You get more usable room i a dome tent as the sides don't slope in so much.
They are a pain to put up, take hundreds of pegs, then triple that if its breezy cos you'll need all the guy lines (there are 2 sets). open the door when it is raining and water pores into the tent as it has no porch.
Mu dome tent on the other hand takes 2 minutes to put up, is warm and light inside. Three pegs to put it up, maximum of 7 for a force 10! i can open the door and get a brew on without getting wet or out of my sleeping bag for that matter.
I honestly think you would be better off buying a quality (mountain) large dome tent.
Is this just another case of RM uses them so everyone else should ? Or maybe they a far better in deep snow as it doesn't mount up on the roof.
Anyway just my 2ps worth i'm sure everyone else heartily recommends them.
Rich :twisted:
