Braid will always cast the best, do to no memory.
Power pro,jbraid,seaguar smackdown
Mono is good with certain brands.
Trilene xl, hi seas copylmer fluro coated line, stren orignal etc.
Flurocarbon is tough at times most will become stiff and brittle in the winter but with kvd line conditioner it will tone that down abit.
I reccomend seagaur red label,invisx, and hiseas fluro.
But it all comes down to what reel you are using.
Spinning gear i go with braid and the monosi reccomended. If your wanting to use fluro use it as a leader not a mainline.
If your using baitcasters just go with braod fluro or the cheap berkley biggame(best bang for the buck imo)
Hope this helps.
fishing is one thing. catching is another
