You've all been very helpful - thanks for your time and advice.
As funds are short, I've decided to opt for the DD - I like the double layer aspect and the fact that it has everything that you need (no need for extras - as limited as they may be). Nick, the owner of DD has informed me that they'll be including netting and tarps very soon, so I'll wait for them (perhaps) and send a review in when I get one.
I'm always careful when buying kit (sourcing the best value for money equipment - IMHO - and rarely impulse buying). Hopefully I'm making the right choice. Anyways, I mod so much of my gear that I doubt it'll survive without some adjustment
Hell, you should see my rucksack, knife holster, dog trailer, et al.
PS I am not affiliated with Nick or DD hammocks - I'm just picky with my gear.
