Lunar duo or double rainbow?

Ive just read the other post on this so I want to reduce my question to- living in a high humidity area which one will handle condensation better?

Be sure and read this excellent research analysis by a BPL researcher:

After reading this, we followed the advice in a Tarptent Rainshadow 2 tent and it worked superbly. To keep your scalp warm when you have that much airflow during the night, wear a lightweight beanie though.

For rain when you have to shut the opening, and you end up getting condensation, use a tent sponge (search REI.com for "tent sponge") to easily take care of that situation. I also use that sponge as a "brush" to clean the tent floor during dry spells too. Very handy and only weights 1oz.

thanks for your reply, really appreciated!
