Drifter: That is another knot that I USED to use to connect PP and mono.

If it locks up tight, you are good to go...but I have also had Power Pro slip out of that knot.

I do use the Improved cinch knot for 90% of my tackle, thought. It is excellent for tying on hooks, etc.

The Uni-Uni has never failed me for the PP/mono application.
