In reply to origamib:
I am no expert, but I got one from Sportpursuit last year. I've not looked at what ones they have at the moment, but I don't think there is a massive difference between them all.
I would go as long as possible, just to give you options, but actually it's really hard when it's long!! We have trees that we sometimes use it on behind our garden fence, and we actually have to extend our line slightly with old climbing rope to get it to stretch far enough, and I can barely do it there. We more often take it to the park and use a much shorter stretch which is much easier.
Good fun on a summer eve with some friends and a BBQ
