After deliberating for a couple months between the Easton Kilo 3P and the StratoSpire2, I ended up buying a StratoSpire 2. I like the Easton's PU fabric floor and freestanding design, but the non-exposed inner setup of the StratoSpire, dual doors, dual vestibules and lighter weight was enough to sway me in this direction. It arrived today.
I just did one quick setup in my (small) living room using chairs etc to set it up. I can't speak to the finer details of this tents setup since I couldn't even really tension the tent with the light chairs I was using, but I am really impressed with the overall design concept. It's brilliant. I like how it protects the inner during setup, how it only requires 6 stakes, and how there aren't guy lines all over the place, since all the stakes are around the perimeter of the tent fly. Hopefully sometime soon I'll be able to set it up properly and actually evaluate the pitch and internal space.
I definitely never thought I'd be back to having a silnylon tent again. I'm fine with it for the fly, but I really don't like silnylon floors (slippery, not that waterproof…I much prefer PU nylon). It speaks to the excellence of this design that I bought one anyway despite disliking silnylon floors. The stuff is indeed slippery and I'm going to have to dot the bottom of my sleeping pads with silicone. At least the bathtub floor of the tent is anchored at the 4 corners. My previous silnylon floored tent (SMD Refuge X) just had a hanging floor that loved to slide around on the ground, so the floor would slide into the vestibule even if my pad was securely stuck to the top side of the floor which I treated with silicone/mineral spirits.
Once I get this seam sealed and get some silicone on the bottom of my pads, I think my wife and I are going to really like this one. It's going to be a lot more livable in the rain than my previous tent, which required the inner set up before the fly and it had a door way that let rain fall in.
EDIT: I nearly forgot the weights. Pre-seam sealing, the tent (fly + inner) weighs 38.57oz. The six stake kit from TT weighs 2.4oz, but I'll likely use lighter ones. The Easton poles for setting this up weigh 5.6oz. So using trekking poles and lighter stakes, this tent will likely come in around 41oz after seam sealing plus another 0.7oz for the stuff sack. 2.6 lbs is pretty sweet for a double wall tent of this size.
