Floris,
Check out how the
HyperLight Mountain Gear Echo II attatches its beak. It seems as if the corners are snapped into place, the peak seems to be located by a grommet over the tip of a trekking pole, a zipper separates the two sides for entry, there are two tie outs pointing rearward adding tension to the sides and the bottom front tie out seems to go in common to the front ridgeline tie out stake.
It is a very neat setup.
Party On,
Newton
