So I've never owned a fully-mesh inner so I spent last week+ searching BPL and other forums to figure out what it would be like. As far as I can tell it is a GOOD thing in warm climates, but a BAD thing in cold climates. A solid inner is barely any weight difference, according to some, a slightly heavier according to others, depends on the fabric. When you look at the added weight, and the quoted temperature increase inside/outside its a worthwhile weight/benefit to have solid inner, vs say a warmer sleeping system.
I also think I know why my TN LC was so damp it had no venting on the outer near the roof. I see the Scarp has these and the Notch does too. A few tents back I had a Coleman Viper and it had mesh with a flap cover on a single-hoop and it didn't suffer damp as much as the TN LC.
So, without buying/trying, as far as I can tell, making a solid inner option, inclusive of the roof, like the Scarp would be a good option to take the Notch down into cooler conditions with a good weight penalty relative to a heavier sleeping bag.
