I have been hanging for about 6 years now, and have slept well in 9degrees to 100+, raining, and more. Having a good hammock is only part of the equation, pair that with a good pad, possibly a wrap for cold weather. the most important is a good tarp, possibly a bug net..
I personally have several brands of hammock and have found my perfect setup..
Grand trunk Funky tarp
eno helios straps
Straps are nice, however I have often used a good climbing assessor cord.. the key is to find rope or webbing that does not stretch.. Eno atlas is the best for 200lbs or more.
(in no specific order)
If you have any questions, want to advice or just compare setups, give me a holler.
