Fluorocarbon is good line with a smaller diameter size than mono. The advantage is in clear water the fish can't see your line, it truly is invisible. It is more sensitive than mono similar to braid.
The disadvantage is every time you get a nick you need to stop and retie, every nick. Because the fish you break off will be the bigger one. It is 3X as expensive as mono and needs line conditioner periodically to run smooth thru the reel.
The water I fish is not clear enough to be concerned with it, I still use mono 90% of the time and some 20lb. Braid.
I use Seaguar Invisx 12lb test for fishing weightless senkos for bass, mostly during the spring spawn. It is $20.00 for 200 yards.
