The Contrail looks ugly, and I'm sorry to say that's enough to take it off my short list.
I carry two trekking poles, so why not use both of them at the front and include just one short pole at the back. Then you could have a design which looks as cute as the Wilson 400 used to. The Wilson had vestibules either side and still managed to have one of the smallest footprints I've ever seen. The front poles went beside the camper's shoulders and the single rear pole was near the feet. Essentially, it was a transverse ridge design with a foot extension. In tussocky conditions, a small footprint can be a big advantage. Tony Wilson built tents to last. He used heavy fabrics and triple-stitched seams so his tents pitched tight and could stand up to a British winter, but they still came in under five pounds. There are still some about even though Tony hasn't sold any for many years.
I'm really liking the thinking behind these single skin/floating groundsheet tents and the bug proofing is starting make them look like something which would cope with the Scottish Highlands. Hamish Brown used a single skin/floating groundsheet design on his record-breaking 1974 epic over the Munros, but it had a down-to-the-ground fly and valances. I see that design as second best to the Contrail/Squall Classic type design in summer, but Hamish's Tulloch Mountaincraft tent worked in winter and also survived a trip to Greenland.
So, a single skin/floating groundsheet with a Wilson 400 configuration is what I'd go for, if someone could work out how to do the bug proofing. Possibly in spinnaker fabric, if it genuinely does get quieter with use. Ray Jardine was right about connection. It is something I relish when tarp camping. With the twin vestibules open on a 21st Century Wilson, your eyes would be able to see what the world was doing just before going to sleep, without any need to bend your neck. The openings would be in just the right place for easy viewing.
Till then, the Squall Classic looks a better bet than the Contrail. Has anyone tried both?
