Both are excellent shelters, but my shelter collection needs some rationalising! Prices include posting from Oz. Can take photos of either shelter if anyone's interested.
SOLD! Squall Classic is the Spinnaker model by Tarptent in conjunction with Gossamer Gear. It's in as new condition with no dirt, damage or smells. Seamsealed. A small MYOG mod was to add a linelok to the midpoint of each side which improves the pitch a little. (There is a small repair to the stuffsack though!) Weight on my scale including rear pole and all guylines is 723g. $250 delivered.
SOLD! Echo 1 includes the tarp, net tent and beak. I bought this as a prototype, so passing it on cheap. Unable to detect any evidence that it's not identical to a production model. This thing is bombproof! I'm just not likely to get full use out of it in our benign climate. Again, it's in pristine condition. Net weight in stuffsack including all original guylines is 677g. $250 delivered.
