Ok my setup is a Shimano Citica bait cast reel. I have been using 12# fluoro line flawlessly until I had a fish break me off on some rip rap. I beefed up to a 15# fluoro and am having horrible backlashes. With the 12# I could turn the break basically off and pitch the lightest of jigs with ease. Now with the 15#  I can't even cast without backlash. It's quite stressful. Not quite sure what to do. I am using the cheaper seguar red label fluoro. Any suggestions or advice would be greatly appriciated 

Try some line conditioner. But that red label won't do you any good in rip rap.

Maybe try 12# AbrazX

Try some kvd line and lures conditioner.  Heavier fluoro tends to be stiffer and have more memory.  I have good luck with sniper and heard tatsu is one of the best.  If you can afford it, don't skimp on line.
