Keith, over the last couple of years I went through a search for the most versatile 2P Hilleberg shelter. I am lucky enough to live close to a couple of Hilleberg dealers so I could set up various shelters side by side. For tunnels I looked at the Anjan / Nallo / Nammatj / Kaitum. For domes I looked at the Rogen / Allak / Staika / Jannu.
As you read on outdoorgearlab, the tunnels have a better space to weight ratio than the domes. I personally didn’t get on with the Anjan or Nallo 2P variants because the slope of the roof toward the foot end makes it feel much tighter down there and prevents two people from sitting up other than right at the door. Thanks to the equal length poles, the Nammatj has much more usable space (headroom and width), albeit at a weight penalty. If you can handle the extra length of the Kaitum 2, that will give the most usable interior space with a pair of vertical doors. The twin vestibules let you can stash your packs in one end and use the other as a dedicated entrance. If you’re sold on the Anjan, then consider moving up to the Anjan 3. Its 7-8oz weight increase over the 2P offsets a lot of the limitations of the latter, being a foot wider and 2″ taller at the door, and 8″ wider at the foot end.
On to the domes. Forget the Jannu for 2P use unless you like being really cosy. The Staika and Allak doors are almost vertical thanks to the toggle design that connects the inner and outer tents, but the curvature of the head and foot end cut down on usable space. Long sleeping bags invariably get damp at the foot end when using a 2.5 – 3.5″ thick sleeping mattress. The Rogen has bigger vestibules, but the inner tent is the smallest of the three. The doors are much less vertical, and they are slightly concave.
In the end I chose the Allak when I need a freestanding tent, and the Nammatj 3GT for luxury base camp use for 2-3P.
