Kurlee, for my fishing needs, yes. When I don't need the extra strength of a braid and want a fast fall rate, I will use just fluorocarbon (fishing Super Flukes deep is one). For spinning gear, no other line type beats braid for trouble free fishing. I fish weightless finesse presentations in heavy cover a lot and braid fits that application, but the braid's floatation limits the proper depth control by itself. A leader of about 4' of 20# is my weight to get that depth control. Water color has no affect on my choice of lines. The presentaton along with the amount of cover and potential catch size determines the line I use.
ww2farmer, I've never experienced any fluorocarbon line that I would classify as manageable, tolerable would be a more appropriate description.
