I have been mass producing Wind-on Leaders for over two years now after picking up the idea from the Southern Cape Boyz. During this time I have made a number of versions, but I think this will be the setup I'll stick to for a long while.
I use a single stand dacron, but have a double section of about 5cm near the top of the wind-on where I believe this additional grip will ensure the mono will NEVER slip.
Enigma's recent 'heads up' on the Tanaka Stitch put the finishing touches to a great wind-on.
If anyone needs more info or explination please add onto the thread or simply drop me a PM.
