Here recently I've had a few fish break me off with my 40lb power pro...I don't know if it's because the line is kind of old or if it has anything to do with me tying a palomar knot and it breaking at the knot.  What do you guys think?  And if it is the palomar, what knot do you all prefer for braided lines?

I use the palomar for braid.  Make sure you inspect your knot after you tie to make sure you tied it correctly.  If you are still breaking off after that I would recommended switching to higher pound braid.

Double palomar knot

Ok thanks guys...after those last 2 posts I think it was just the line...it was kind of old.  It has only been just within the last couple months that this was happening and only when I was using T-Rigged soft plastics.  I've since bought a new spool and I'll go from there and see how it works out.
