I've been looking for a fast, small, strong knot for the braid to mono connection. I found this knot that is named after "Crazy" Alberto. He is an avid surf fisherman and photographer from the east coast.
Sometimes when things get crazy and you need to tie a knot in the wind while your buddies are all hooked up can make you crazy. I can tie a bimini in about one minute. A Uni to Uni takes about 25 seconds. This knot can be tied in thirteen seconds and is very small and strong. It's smaller than a uni to uni.
I tied it ten times with 80lb braid to 80lb mono and I couldn't break any of the knots. It is easy and fast. Very little practice is needed to perfect the knot. Give it a try. I like it.
