The twisted leader to bimini is looking very promising. I have also been playing with a long nail knot on the leader for single strand. Again very promising but only seems reliable for PE8+ and 200lb leader +
Go to www.bptackle.com and you'll find everything you need to know about making windon leaders. Basil pappas will tell you everything you need to know and the only knot you'll ever need is the one to the hook.
BHP has some good info. Blackwater International does also. There are links on research here: Links on Splicing. Making wind-ons is different than knotting. Learning a good test protocol is important to getting the result you want.
