I just recently learned of this knot and it is far superior to a double uni when attaching a leader to braid or maybe any line. I always thought a uni was the way to go till some random guy I meet showed me how to tie a grinner and pointed out the flaw in tying a uni to connect a leader. It took a couple tries to get it down but know I feel more confident in my connections and it is supposed to be a 100% knot. It's like a uni and clinch in 1 knot and if your looking for a new knot might be the way to go. From know on this will be the knot I use for any line to line connections I make unless I find a easier 100% knot someday.

How slim is the knot? Any videos on it?

Here is a video.... I prefer the Alberto Knot myself.

I really like the Alberto. I never had any problems with it and its easy to tie.
