TT Double Rainbow or Terra Nova Solar Photon II for Winter?

My winters are wet and around freezing, like you are describing.  From my experience, I’d be more comfortable  (especially on longer trips) in the TN.  I hate to say it, cause I love TT, but in my tents (mostly mesh) the dew point gets me often, and my bag gets wet.  Nothing serious, but I have been wanting to get a solid inner for my Scarp and be done.  The DR should be fine for a couple of nights, but in my experience, much more than two nights of those conditions and the wetness starts to degrade my loft.  I have no experience with TN, but this is about physics, not tent design.  Frankly, from all the things I’ve read about TN, I’d never get one even though I believe they are constructed well.  But in usage I’d go with the more solid walled tent to stay dry over multiple nights.

That being said, buy a solid inner Scarp 2 with the crossing poles and watch your TN get dusty.  (Where is The Gear Enabler when you need him?!!?  B2W!!  Help! A Tarptent need to be bought!)

EDIT– Just read that you have bivys.  The Scarp with no inner and bivys is cool too.  Cooking in there with no inner is  awesome in winter

Thanks for the thorough response.  I do wish I’d been more pointed with my purchases (like tarptents more expensive offerings or a Duomid), rather than hopping on good deals on gearswap.

Not sure about pushing the dew point and all of that..
In my experience I have woken up dryer in my bag inside the Rainbow/Moment (single wall) and Notch (mesh inner) than some of my neighbours inside their fully sealed “4 season” tents.
For example , here :

I woke up dry but removed a sheet of ice covering most of the sealing area (on the inside), my mate did well inside the Lighthouse (Epic, single wall) but a few meters away 3 guys inside a fully sealed up double wall tent were cold and dump and so were several others we met inside the nearby refuge .
(the temperature was a touch above freezing the previous evening and below freezing at night)
BTW, you can pitch the DR very low , like this :

“but a few meters away 3 guys inside a fully sealed up double wall tent were cold”

…is the opposite end of the spectrum.  Both are wet for different reasons.

Dudes need to vent, one person in a mesh needs to seal up a bit.  …For optimal results.

Thanks again for the input.

Franco, I watched several of your videos and learned the trick to dig a hole to bury the DR pole. I don’t recall exactly why you did that, but its one thing Ill keep fiddling with to get a tight seal. Thanks for posting the video.
