Welcome from Scotland, your head will be whirling in no time... whoopies are where it starts, I've only been a member for a few months and I stuck thinking about hammocks constantly now.
You should check out the diy section if you're looking to reduce hammock weight, the DD camping hammock weighs 650g on its own, a 1.5oz diy will weigh max 350g probably more like 300g (I'll find out when I get around to making it) and is very easy to do.
