I've got a Oztrail Mitchell in a king single and a dble swag.
They are such a bad design with the 3 loops, the middle loop has to be put in with the swag unzipped and your bedding exposed to the elements while you fumble trying to get the stupid loop in place. Then both ends have to be pegged and roped. Wish I had got the spreader bar style.
The only thing I really like is the canvas base as it doesn't pool condensation like the PVC style base.
