I'm with Bob on this one.
"Interestingly, they also recommend the four-turn surgeon's knot for attaching the fluorocarbon tippet to the mono leader. It works well, using the wetting/tightening action described above. Prior to that I had problems with tippets breaking at their junction knot"
To build leaders I'll use a good old barrel knot, to attach tippet materials (especially if it's going to be fluorocarbon) with a tripple sugeon's knot. Interesting the 'do it quick' part on snugging up the pieces. That I didn't know.
