I've owned one of these for the past few years. Got mine at an REI garage sale (the only thing wrong was it was missing the pole). So I've never used the carbon fiber pole, but it sets up great with two trekking poles. I have wished for a non-conductive pole when waiting out severe thunderstorms above treeline, however.
It has been through heavy rains, hailstorms that left 2 inches of hail on the ground, and all-night snowstorms. I've found it to be great in every condition except heavy winds. The only times this has been a problem is when camping above tree line, and I found that even in light winds it can flap a lot, making it difficult to sleep.
Condensation has been a major problem only when I've pitched it over wet grass. That's when it did some dripping. Otherwise, it will get a bit wet inside on a still night, but not dripping.
What should be improved?
1. Add some guy-out points midway up each seam. This should help with flapping and in high winds. I'm looking at doing this myself, but it would be nice if it was done from the factory.
2. On the corner strings, some kind of taught-line hitch setup could work to make them easily adjustable. I've used the doubled stings (not tried triple), but that only gives fixed lengths and sometimes there are rocks in just the wrong spots.
