Excellent points SuperA and MTarrowfinger. Thank you both.
I like the modular design and thought about the LBO but couldn't find any YouTube video I liked that displayed the interior size by itself, with a vestibule, and a base-to-base. I'm visually oriented and if I can't see, I won't understand it.
The other consideration is that I's like to be able to backpack by myself with the tent if friends are busy and can't go. That would mean all of the weight must be carried by me. A pound and a half isn't the end of the world, nor is $450, I was just trying to have the best of all worlds.
I should know better and, in the end, I have to decide what priority each characteristic...weight, cost, room, and tent size...play in my decision.
