They say that some of the pure floro lines are a lot better than others. I have never used a pure floro line that I thought handled that good. Guess I may have not tried the right one yet?
There is an alternative. P-Line makes (2) flourocarbon coated lines that handle very well. (Flouroclear, and CX Premium). I use both of them a lot, and really like them. Of coarse there are other people on here that absolutely hate them. They work well for me in many presentations. I mainly use the 12#, & 15# in both of them. They are not the best choice for all presentations, and fishing conditions. But, They work well for quite a few, and handle as good as any line I have ever tried. Just my humble opinion.
