I am in the market for a tent and think I've pretty much nailed down what I'm looking for but would love some other opinions.

I am looking for a 2 man backpacking tent; it will mostly be used either solo or with one of my kids but I forsee the ocassional trip with another adult. I am looking at 3 season tents, but plan on pushing the boundries a bit (e.g., late/early winter) and it must be able to withstand a good storm. I will mostly be using this in the Alberta Rockies, maybe a bit on the BC side (where constant rain seems to be my fate :)).

So, for critera in selecting a tent, I've come up with:

• 2 entrances
• 2 vestibules sufficient for a good sized (i.e., 70-80 litre) pack
• Vestibules which allow opening/entry without getting the inner tent wet
• At least a partial-fabric inner tent (i.e., not all mesh)
• Vents in the rain-fly
• Wide enough for a couple Therm-a-Rests for the full length of the tent
• Under 6 pounds
• Around $300 or so (preferably a little under)

So far, this is leading me to something along the lines of the MEC Gemini .

What I'm wondering is if there's something else I should be looking for? Or is there something I'm including in my criteria which isn't necessary or is too restrictive?
