I use climax which I get from spirit river. I am on my first spool of 2 pound test and it really really sucks. Maybe I just got a bad spool? Maybe I am just unlucky?

Anyways I will tighten a knot and the tippet will break, not at the knot, but on the tippet. And its not a case of my pulling to hard. On the good sections I can pull even harder and have no problem.
