Double Uni Knot

[desmobob]

If it is not good for different diameter lines then why is it the #1 knot for fly fishing? The difference in diameter in fly line to the leader is massive compared to what would be used for bass fishing.

 

It's used to build a tapered leader... each section you tie on is only slightly smaller diameter than the previous section.  In other words, you're always using it on similar diameter lines.  As J Francho noted, it is NOT used to connect the leader to the fly line.

 

If you take a good look at a blood knot, I think you'll see it's just a clinch knot-to-clinch knot connection (not "improved", just the standard clinch).

 

Tight lines,

I run braid on all of my rods and use leaders on almost all of them except for jig/topwater. I used uni/uni for almost a year but was not satisfied, it was good 95% of the time but this is fishing... I switched to alberto's (modified albright) with 7 wraps up, 7 down. Once I practiced I could tie it about twice as fast as the uni/uni. I always retie leader connections between trips which with any knot you should do.

 

My leader connection never fails even when pulling straight back out of a snag. The leader will always break near the lure (not at) so I can tie a new lure on with the remaining leader and I am 100% worry free. The only time i retie the leader is if it is too short or if the knot is visibly damaged from cover which is exceptionally rare. I have 100% confidence in the knot but not the uni. It is funny because the regular uni knot is not recommended for fluoro so it makes me wonder why it is recommended in a connection to fluoro.

 

The alberto is easy to tie but hard to master there are a few tricks I do that ensure a good knot every time but would be hard to explain over text so I might just make a video if anyone is interested though there are many videos already out there.
