I want to get more into finesse fishing this year. What knot do you guys think is best for say 15-20# braid with a 6-8# fluoro leader? I should add I use the Alberto knot for heavier line. I figured you would have to wrap too many times on light line.

I'd give the Blood knot a whirl, and if you don't like that go with the Uni. 

I tied an Alberto using 10# PP to 10# Sunine Super Natural using 7 wraps both ways last Saturday for panfish and it worked fine.

Stick with the Alberto.

Blood knot is good but a carefully tied uni knot with some superglue on it will do the trick.

The alberto still works fine for me. 

Knot Wars winners in the light line category were Alberto (Modified Albright), Uni-Uni and J-knot.   Try all 3 and see which you like best...all are strong ~

Alberto and J-Knot both work fine for what you are wanting to do, as does the Seaguar knot. I personally don't recommend the uni-uni, though many use it without issue. But any of the 3 mentioned will work well. I've used them all with much lighter line/leader connections than what you are proposing.

I used a uni knot on 65# braid with 20# P-Line leaded. It worked great but it was kinda big. a Pain in the butt.

FG knot works good.  Others with more experience may comment on its light line effectiveness.

I use the Alberto for everything from 10# braid to a 6# leader to 40# braid with a 15# leader. It never lets me down.

FG knot works good.  Others with more experience may comment on its light line effectiveness.

The FG knot does look interesting, but if the Alberto works fine, I'll probably stick with it.

Thanks everyone.
