I Have the DD Travel Hammock and the DD 3x3 tarp A Great set up, i use 2x Snap gate Karabieners (load bearing ones) to set it up
I also have the DD Hammock sleeve which is great, it allows me to store my Hammock and my Tarp together and putting it up is easy, and quick.
I use a Rollmat for insulation and slip it in between the layers - does me just fine
I love mine it is really comfortable, I started with the Issued Basha, and its good if there's no rain but other wise it helps your hammock become a water collection device.
Hammocking in the Cold does produce a lot of condensation, i use an Issued bivvy bag on my sleeping bag so it stops me from getting wet, however the condensation aids in taking heat from you and could make you cold.
If i were to buy again I would get the frontline, it eliminates the condensation issue and has an entry on both sides other wise its just the same.
I have also invested in the DD XL Tarp 3x4 as it gives me an admin area, but i mainly use this tarp when I know fowl weather is coming other wise its a bit big.
I use a metal coat hanger cut and bent to fit the mozzy net, it saves you spending ages looking for small strong sticks.
I have also attached a long length of cord to the zips it makes closing it so much easier and saves me stretching...
To set it up initially i simply tied both ropes together every 10 inches, then i wrap it around the tree and using the Karabieners i attach the rope to it's self.
The best advice i can give is a DD Frontline Hammock, DD 3x3 Tarp, 2x Karabieners and a rollmat, oh and a sleeping bag.
Simple and cheap enough.
If you find Hammocking is for you and its regular then maybe look into some upgrades, no point spending money if its not for you.
