If you like the layout of the boulder2 (I wasn't aware of it - had to look it up) I'd consider the Robens Lodge 2.
Great tent.
Better colour in my opinion - green - I hope my cycling adventures never get to the state where I have to be picked off a mountainside by a helicopter so I prefer to be as inconspicuous as possible.
The Lodge 2 is also essentially freestanding - it does come with guylines but you don't really need them - so less faff - and less to drunkenly or soberly fall over.
