I've got an MLD Superfly that is the same configuration (although a lot lighter) so I have some experience with the shape. Next to my Hilleberg Soulo that IS made for expedition (read: high alpine, 4 season use), it is a tarptent at best (and I say that lovingly) for 3 season use.

And I didn't say that was your take on the tent; only that the classification by MSR for that shelter is ridiculous.
