WF Leaders and Leaders in general
I've used them in the past, and they DO work well. I haven't had occasion to use 'em lately though. Less wind where I live now.
I've tied leaders since I was a kid, and enjoy preparing several for a special trip. I have cut down on the number of reductions in mono diameter, going down in fewer steps - and with VERY good results. Depends on the knot used, I guess!
I use A.J. McClane's old formula of 60 % butt, 20 % taper, and 20 % tippet. It may be old, but it still works very well.
