My system is currently working but I have been thinking about reducing some weight lately. With an exped SI mat sized large for big blokes, mozzie dome, tarp and heavy duty ground sheet for rainforest floors I am at 4-5kg+ not including the sleeping bag. I was hoping to cut some weight( possibly with a hammock) and enjoy the other benefits of being off the ground. Thanks for the suggestions last year, I was wondering if the experts like Nq111 etc above might be able to help with some further questions.
-Any good suggestions of a moderate priced hammock, double lined , that might suit a 6'3" 110kg footy player build sleep wriggler?
I usually go for army type equivalents, that is not necessarily the lightest or best quality but generally decent performer for the price point.
-I have a 10ft x 10ft shelter tarp by snugpak and wondered if this would compliment the hammock or should I go smaller or larger for all round use or do hammocks need something specifically hammock compatible?
-I'd like to press the hammock into service in more open southern areas , mountain/wooded country and wondered if it can handle slightly sub zero temperatures. I assume for cooler weather people use mats etc in the hammock anyway to insulate the bottom?
I'd assume its not the best choice in storms but with a decent tarp can it be configured to handle some slanting rain and wind?
You can see I am angling for rainforest with some general 3 season all roundiness...is this a realistic goal?
I'm going to do my research on them properly, but thanks for any general advice to start with

Nice, I think you'll find Hammocks suit your requirements very well.
I'd recommend looking at the Warbonnet Blackbird XLC DL 1.1 (XLC = 30cm longer than standard; DL = double layer). They're a fantastic hammock, though I'm only 5' 10" so I can't comment on how well it would fit you. They're supposedly suitable for sleepers up to 7', but you know how manufacturer recommendations go. The DL 1.1 should keep mosquitoes from biting you through the fabric, and will allow you to slide a mattress between the layers for some warmth/protection if need be. The DL 1.1 is rated to ~125 kg I think.
Any tarp should be fine for a hammock, though you could potentially save some weight by going for a hammock-specific tarp designed to have a high ridgeline and to cover a hammock end-to-end (the WB BB XLC will be >10' long). Most have a caternary cut for tighter pitching and optimal weight to coverage ratios. The Warbonnet Superfly would be my pick for the tropics; when it rains it pours, and you need space to move/cook/chill when you're shelter-bound. When it's clear, I wouldn't even pitch it.
Sub-zero temps are no problem as long as you're prepared. A mat below you will help, but realistically you need an underquilt (which hangs below the hammock) as well as a regular quilt/sleeping bag (a quilt is preferable). I've always gotten away with just a mat + sleeping bag in my hammock (Hennessy Ultralite Backpacker) but I've never used it in super cold conditions.
Heavy rain is no problem as long as your tarp is suitable. In fact, in torrential rain I've been perfectly dry using a tiny diamond tarp - just pitch it acutely over the hammock. You don't need to worry about pooling rain or anything like you do in tents. Make sure you have driplines set up to prevent water running down the ridgeline into the hammock.
Your goals are very realistic, but don't expect to save a huge amount of weight with a hammock setup over a similarly capable tent (e.g. Tarptent Notch). They can be more versatile in some circumstances, and less in others.
