i like the carbon line for a few reasons. its almost invisible and its very low stretch and sensitive.
when do i use it. on my pitching rig, on my spinnerbait/rattle trap rig, and on my crankbait rig.
i will never spool carbon on my spinning reel again. been there, dont that, big mistake. perhaps there is a secret i am not aware of, but i had nothing but problems on spinning gear.
because it is so low stretch, i feel the line isnt as shock absorbant as the makers may claim. i use stren flurocarbon line and found that when first using it, i was setting the hook way too hard. i was having some breaks also in the beginning. but once i realized that it only takes have the power as mono to sink a hook into a fish, my problems disappeared.
i have tried every line out there about and have always came back to using mono. really, you cant beat it. but carbon line replaced mono for some applications for me anyway. if anything, if you pitch at all, i would at least give it a shot on your pitching outfit.

ps: i am no expert either. just my opinions
