When I use fluoro I use Seaguar. I've had more than one bad experience with blood knots so I use a uni to uni connection. I've tied this not with mono to mono and then wrapped it around my foot and pulled and everytime, the line would break instead of the knot, so I've got confidence in this knot. I also tried the same test with the blood knot, and the knot would always break. It's all about confidence though, I know rob likes the bloodknot and he hasn't had any problems with it so that's cool. I've had problems with it, so I don't use it anymore. Same deal with line, if you never break fish off with Maxima, then why switch to P Line? Try a few knots, pull on em, fish em and see which one you like best.
