2mm dyneema for my ridge with dyneema prussic loops.
One thing I have found out about Dyneema it has quite a low melting point, i.e. from fricton when it rubs... have a had a few kite fly off when the lines tangle
still good for stength tho...
Is the kite stuff uncoated Stu?, I know the stein arborist stuff has a poly coating to help it stand up to friction better.
Some cracking kites there mate. I bought 1000 yards of kevlar kite cord from china which was about 200lb rated. Makes good sewing thread
