Having decided to get up in the trees for the first time I would like your learned advice and opinions please. Along with the kit you use and the kit you recommend. Thank you 

I'd borrow someone else's to try it first of you can. Tw super xl is a very comfy hammock and cheap. No bug net though, but I don't tend to use mine on my other hammock.
I've had a DD travel but I had condensation issues. Although others don't. I have a tw grey hornet. And it's good. But my cheaper tw super xl is now my goto hammock. Packs small and light. Flat lay. I swapped out the suspension for whoopies and tree huggers. For the super xl you'll need at least a 3.5m ridgeline on your tarp.
I've tried a hennesy asym deluxe and I think the super xl is at least as comfy.
