Fluorocarbon Fishing Line Quality?

[LSU Fan]

Like to know what I am doing wrong?  I have tried almost every brand of Fluorocarbon line out today and have not had it last more that 3 weeks before finding it breaks.  I usually use 10-15 # line depending on technique.  I had fluorocarbon line on both Baitcast and Spinning reels which had been stored on my boat in a carport out of exposure to direct sun.  I have lost some good fish and just recently lost a tournament due to having a real good fish break off due to broke fluorocarbon 12# line.  I had just tied to braid using a double uni knot not 8 hours earlier.  Now the strength line I use is 10#-15# depending the technique.  I've had this concern several times using fluorocarbon line several times and have know stopped using the line till I find some answers.  How I test the test is a bit broad, I tie an overhand line wet the knot and slowly pull it tight by hand.  I then pull slowly increasing outward.  Depending on line strength how soon I expect the line to break if at all.  Again I would like to know what I am doing wrong?

So are you using it just as leader or as your main line?

It sounds like an equipment issue to me.  Check your guides for cracks or burs.

When I first started using fluorocarbon, i found a similar issue. Breakage usually happened in two ways. It was either the knot, or wherever I had a kink in the line which could have been a bad backlash, snag etc. I initially gave up on it altogether. But I have since switched back to flouro for techniques such as jigs, plastics and whatever other technique where line stretch, sensitivity and visibility would be an issue. But I constantly inspect my knots and my line for weakness or fractures. When in heavy cover, I often re-tie after catching a good fish. 

Maybe try a new knot. Also, check the diameter of flouro to the size braid you are using.

Personally I use straight monofilament (Trilene XT 14 - 17 pound test) on my baitcasting combos. I do not like Flouro for a number of reasons but those reasons have been debated ad nauseam on this forum already.

Several really good river smallmouth sticks I know do use the braid with a flourocarbon leader setup. What I have watched evolve with them as that they have started using a quality flouro with a minimum of 14 pound test. One of them uses 14 pound test for his "finesse" presentations and bumps up to 20 pound test for jigs, swimbaits, spinnerbaits, etc.

Check your knots, line for abrasion, and guides.  I'm not a betting man, but if I were, at least one of these is your issue.
