Hello Don and Ken,
Don, many thanks for the US source, if I get desperate, I can always see if they will post to the UK. Ken, not sure if the Stealth Brand is available here but I can have a look and see. I was given a lead, by a UK resident, but that stuff was green and I have problems enough flying over grass with normal lines. If I had the green stuff I hate to think what a mess it would be.
I may have missed it somewhere, but no one seems to give the material that Spiderwire is made from, apart from the fact that it is braided, there doesn't seem to be a generic chemical name for the stuff, the fishing tackle man I was talking to seemed to know his stuffwhen it came to the chemical names, he grumbled that there was so much different stuff being marketed under the same overall Brand name but different materials!
I am impressed by the fluorocarbon monofilament material, very smooth tangle free material. It does break but you need to give it a good sharp pull. It goes at the knot .........but the breaking strain is only a little less than the line itself. For the featherweight plane that I have tried it on it seems a very good solution and it is quite inexpensive. I will let everyone know when it lets me down!
Regards,
Andrew.
