In reply to Stani49:
Assuming you are on ground where you can pitch it tautly and firmly, they're pretty good. Heavy snowfall might tend to make them sag outer onto inner, but wind shouldn't be a problem unless you can't get good purchase for guyline pegs etc. The key is to make sure the hoops can't move inwards towards each other.
The only other negative I can think of is that the small porch and side entrance may mean snow/rain get inside the tent. Less of a problem if using the "3" person 300 solo I guess.
I use a Halo 200, same fabrics and poles, but semi-geodesic and therefore freestanding. A good design, and pretty robust, but after 3 years heavy use (approx 30-40 nights a year in all conditions), its just starting to feel its age and this is where its not as tough as a more expensive tent I feel.
