I think it looks great. I'm hoping that the 2 person Haven tent is just like this but wider. The trekking pole layout looks perfect for giving great headroom yet not blocking the doors.
The Vamp tarp weighs 16oz, the Vamp net tent is 11oz and then you need 5 stakes (~1.5oz) for a double wall weight of 28.5oz. That's pretty impressive when you consider that the TT Moment also weighs 28.5oz, yet that's a single wall shelter (which doesn't use trekking poles).
I wouldn't be surprised if SMD eventually is able to bring the cuben version of the Haven to the market for under 2 lbs. Considering that the cuben Refuge X weighed 16oz and that included a silnylon floor, I'm guessing the cuben version of the Haven tarp will weigh 12-13oz. The Haven net tent will probably weigh weigh 50% more than the Vamp, so about 16-17oz. That's a total of 28-30oz plus stakes. The initial silnylon Haven tarp will probably weigh more like 20oz for a total initial weight of tarp, net tent and stakes of ~38 oz.
