Steady on Ed h, me sensible? MLD Trailstar, MLD Bug Bivvy, MLD Patrol Shelter, MLD Serenity Shelter?? And now attracted to a Cuben Trailstar!! Doesn't sound sensible to me.
But Aguirre (Gordon) and MfD are spot on regarding the flexibility the Trailstar gives re pitches. It is a big footprint, but it simply swarms over tussocky grass and boulders that you could never do with a trad double skin tent or maybe a fixed inner. Once the Trailstar is up, you pick your sleeping position to suit the ground conditions. You have already eyeballed the likely choice when selecting the place to pitch.
That for me is the big advantage over the Patrol Shelter, where you really want to pitch it tail into the wind and sleep that way, feet to tail, head to beak. But that doesn't always suit the lie of the land. The Patrol Shelter is still a great shelter though
