I've been using 3.5mm D12 for the stays and 3mm for the trapeze for 4 years now without any traumas or problems. I've now refined it to a stage where I no longer have adjusters as its just as easy to adjust the line lengths. Its cheap, easy to adjust, easy to splice, hard wearing and very very light in weight, I'm surprised that more people are not using it <img src="http://www.catsailor.com/forums/images/graemlins/cool.gif" alt="" />
