I'm curious how you feel about doors in general, and specifically, on cuben fiber tarps?
I run a Hammock Gear cuben fiber tarp with doors; it's the 12 foot model that I purchased when I had a longer hammock. I love the tarp, there's plenty of room, even extra room for hanging out under it on a rainy day. However, in pursuit of an ever lighter pack I'm thinking about buying a cuben fiber tarp that is shorter, say the standar 11 feet and possibly foregoing the doors to save even more on weight. I'd keep the tarp with doors for winter or monsoons but use the lighter, shorter tarp for my ultralight set up.
I'd be curious to hear from you veterans who've had tarps with doors and those without. I'm in Missouri and we do get some strong storms/rains so doors do have an advantage.
Finally, who makes the lightest weight cuben fiber tarps? I noticed that hammock gear doesn't even post weights on their site.
