For 6 to 12 lb mono, I cannot tell that any of the premiums like Stren beat the BP Excell. Plus it's cheap enough that you can change it several times per season.
I am losing feel in my finger tips, I bought one of these at BP and learned how to use it. I have never had knot fail, whether leader to braid or mono to mono since I began using it. There was a time when feel and eyesight were good enough, but now I need this and reading glasses:

It really does a better job than a blood knot when joining 2# leader to 2# SOS mono and makes a great fluro leader to braid connection.
