Well thanks for all the great tips and techniques for splicing. I finally found some suitable wire (for those in the UK, try using some 13amp fuse wire, 0.5mm dia). Once I got the hang of it, it went pretty speedily, as other posters have said the secret is in feeding the bury a little at a time and not letting it bunch too much. I put a 2" loop in one end of each piece and a back splice in the other, I'll see how I get on. Anyway thanks once again.
