Hey all, I know there are a few experts out here and I need some help! What is the best knot to use to connect 20 lb braid to 15 lb flourocarbon? The diameters aren't all that much different, basically connecting 6 lb to 15 lb. What's the best way to go? I don't care if its tough to tie as long as its strong.

I tie a Double Uni and it works great. I make three turns on each side to get as low of a profile as possible and it's never slipped.

Maybe it's the line.  I use power pro, but my double uni's have slipped on occasion.  I was using 5 turns on the mono side and 7 on the braid and still they would occasionally slip.

I now use a blood knot with 7 turns on each side and add just the lightest touch of crazy glue to the braid.

so far so good.

I use opposing nail knots, it's a hassle to tie. I use a little tool that makes it easier. Very strong.

I use braid with fluorocarbon for 90% of my fishing. I use the uni-uni knot connection with 6 turns on both lines. The line sizes I use are 20# and 30# braid with 20# fluourcarbon for all waters (super clear to muddy). Never had a knot slip or break when fighting any fish. I just tie it S-L-O-W-L-Y and lubricated, I trim the tag ends flush and the knot passes through the smalles of rod tip guides.

I do uni-uni + superglue I don't have mayor problems.

I ended up going with a 7-turn uni-uni knot. Took it out today and caught one crankbait fish, seemed to hold up fine but we'll see after a couple dozen more fish. Thanks for the help guys. How strong is the nail knot in comparison to the Uni?

Uni to Uni is what I use too.

Only thing I have found is that you need to keep the braid and mono.flouro close to the same diameter of the braid, if the mono/flouro is to large sometimes the braid will cut the mono/flouro at the not.

I generally use 20/6 - #8 Flouro - 30/8 - #10 Flouro.

This is the main reason I use the opposing nail knots. The nail knot is best for connecting lines of different diameters. Also, the opposing nail knots tie each line to the other (two knots instead of one). A uni knot can only be tied to a loop, eyelet or another uni knot. You can't join two lines with a single uni knot. With uni to uni you still have only one connection point where the two loops overlap. A single nail knot can join two lines together very well. With opposing nail knots, in theory, one knot could fail and the opposing knot might hold and both knots create a slipage stop for the other. This is especially desirable with braided lines. Well tied braid doesn't break, it slips apart. JMHO

I use mostly Power Pro on all my reels. I use an albright knot to attach mono. Never had one slip. Inside the Power Pro box is a brochure with knot diagrams, and recommendations for use. I've tied 50 lb. Power Pro to 6 lb. mono using this knot without ever having problem.

If I could figure out a easy way to tie that nail not, there is no doubt thats what I would be using, but for the time being and what and how I fish the Uni to Uni works fine.

Back-to-back Uni-knots will join anything-to-anything.
