MLD Duomid — 640 grams (sealed)
4 stakes — 44 grams
Tyvek ground cloth — 140 grams
Probably about 15 nights so far. Not that I "love" it, but I have not found anything more compelling yet.
A large floorless pyramid allowed me to start eating breakfast w/o getting out of the bag, which is a big deal when it's cold outside (very often in desert environments with large day/night temp difference).
The issues with this tent is difficulty setting up when stakes don't work (rocks) and a relatively large footprint. Also, in a severe thunderstorm with wind I had to worry about rain blown in via the gap between the ground and the tent edge (even though I had tried to get as close to the ground as possible). That same torrential rain I did not seal the seams yet and after a few minutes seams on windward side leaked, learned my lesson, sealed.
I had Duomid in some snow, perhaps a couple of inches of wet heavy snow. It was interesting, even though the tent was not really taut, it did okay. Sealed itself on the sides, some condensation, but really warm, I liked it.

For other uses my go to tent is MSR Hubba Hubba. It's around 2kg and is very easy to set up and completely weather proof. Wind resistance is great, as long as you use 2 extra guy lines.
For family camping I also have MSR Mutha Hubba (got it on REI sale) and it's a nice tent as well. A little fussier to set up, but very good in winds. The tent survived a wind storm in Utah where generally non-flying gear (like shoes) was strewn hundreds of meters from camp. I don't want to throw numbers, but I would say may be 70mph gusts? Well, exaggerating a little :)
I would like to get BD Firstlight if it were cheaper and a little sunnier color. The footprint is smaller and the tent is fully enclosed, which is a big deal in desert. A little heavier, though. Setup is a big pain. If they change color, I'll finally get one :)
