I hiked the southern 300 miles of the AT last year. I used my Clark Camo North American hammock w/ XL rainfly most nights, and found the setup straightforward, using Black Diamond Nutrino carabiners and dyneema whoopie slings, and tree huggers. I slept comfortably in 25 degree weather using an Exped Downmat 9 DLX and down bag.
I did this hike to celebrate my 60th birthday, and will do the rest of my hiking on trips with my wife, so no longer need the equipment. It's only use was this one hike (one month), and is as-new. If anyone is interested, I will sell the hammock complete with extra hardware for $300 and the Downmat for $130.
I'd post this on "for sale", but I don't have sufficient post numbers.
