What I have found when using fluorocarbon on baitcasters is that I have to increase the spool tension a little as compared to regular mono. That is due to it's higher weight and slicker surface, especially on a long cast. When using it on spinning tackle, I don't put as much line on the spool as I do with regular mono and that reduces the excess line that comes off the spool when casting due to it's stiffness. Gently pulling the line to straighted out backlashes with baitcasters or snarles with spinning gear will reduce the kinking damage. Since I threw away all the Vanish I had and purchased BPS XPS fluorocarbon, I have not had any breakoffs from kinked line, or any knot failures. When switching from one type of line to another whether it's from regular mono to fluorocarbon or braid, you have to adjust your equipment and it's use to match the line type.
