I have been thinking about trying florocarbon on one rod and reel that I use a lot in clear water to fish a swimbait. The line is said to be hard to see underwater and sinks, which will help the swimbait stay down on the retrieve.  Flurocarbon line is a complex subject so I found a good objective reviewing spot on the net http://www.tackletour.com/menulines.html , two good in depth articles at this site. There were large differences in the performance of different brands.  Taff was also nice enough to give his perspective since he uses it. I’m still a little confused because there are so many factors to look at: line brand,  price (much higher than mono), wet and dry strength, abrasion resistance, underwater visibility, wet and dry stretch, and knot strength just to name a few.  The only definite conclusion is the Palomar knot holds the best, but still less than 90% than the line’s rated strength. One important subject not covered is castability.  That may not be a big issue with a swimbait as they are big and heavy and are lobbed rather than cast.  I am nervous on that subject however because I am a professional overrun specialist. Line conditioner may come into play in this regard. I hate to say it but some professional fishermen have been winning using the stuff.  It’s one of those things you might ignore but at your own peril.  I’m still confused but I am narrowing the field.  Am positive on two things so far, Palomar knot and line conditioner.
