hi simon, i am on the dyneema band wagon. its light, very strong and very neat when spliced correctly. you only have to see how its done once, and you can splice it yourself easily much like a waterski rope splice. as most guys who know me, i am probably the heaviest mossie sailor(ever)! shutup! and i have never had a problem with it. if you go fishing it is exactly the same as spiderwire, just bigger.
