TT Rainbow?

I had a Rainbow, and for me it was too much of a condensation collector.

Given your parameters, I'd go with a TT Notch. Should be close to ideal. I'd get the "partial solid interior"… me, I've got a BA Copper Spur UL1 that's going to get Fibraplex poles. Will come in sub 2lbs, but definitely more $ albeit freestanding.

Have used 5 years previously a TT Rainbow, have gone to the Statospire 1, two entrances, huge vestibules, similar weight and can set up just the fly, or the mesh inner. Interesting design. My 80 pound Boxer fits fine inside with me. Very rain storm proof, can't speak for snow..

Am 6 feet tall use a 20 inch wide full length pad..

Joe,
This is a still from the 3D video on the Rainbow product page :

watching the rotating tent should be easier to see how that 6' dummy fits inside the shelter.
If where you hike humidity is a problem, there is a liner (about 4oz, $30)made of water resistant breathable fabric, that you can clip in to cover the side and roof area so that you would touch that and not the fly.
However the Rainbow has plenty of ventilation options if you want, you can pull the non door side out, lift the door panels up (or leave the door partially open even in the rain) as well as lifting the ends up (the floor can be clipped up on the non door side and both ends)

BTW, the current version has several changes from the previous ones , the one designed in 2005.(like mine)

I can't answer the questions about TT's new silnylon, but I'm on my seventh season with a Rainbow and am 6'5" tall, so I can speak about the Rainbow's design. There are very few tents out there with as much room for a tall guy, even without the 2-lb requirement. Plenty of height for sitting up, lots of shoulder room for changing clothes and such, lots of room on either side of the mat to put stuff.

I have only two real gripes about the Rainbow: it only has one door and you can't leave that door open in a calm rain. (Yes, there's an awning mode for the latter, but it's extremely hard for a tall guy to slither in and out with that thing deployed.)

I've been told by Henry and others that a Notch would address those gripes, but it does so at the expense of a third of the floor space and some off-peak height as far as I can tell. The dual vestibules might counter some of the floor space loss.
