What Brad said :D
I've spent many a day in a Supertarp with Annex and with a Kifaru Parastove. The whole shelter with the stove and pipe is right around 5 1/2Lbs. I borrowed it from my buddy Ed for bow season last September.
Now if I was going to spend the money, I'd be more inclined to go with a tent from Seekoutside. Kevin is for real and a great guy to do business with. If you're dead set on a Supertarp then look at the "Breakaway Tarp" in Kevin's lineup. If you can pack about a pound more, then the BCS at 80 square feet is worth it. Pair it with a titanium stove from EdT and the whole tent goes the same weight as the Supertarp, but with true 2 man capabilities (its going to be tighter than a Sawtooth)
Then there is Kevin's new tent that is still in prototype phase, known as the Little Bug. It will be sized between a Supertarp and BCS.
Here's a thread on the BCS and Sawtooth.
