My .02 cents, I tried flourocarbon as a main line on spinning reels, both freshwater (4lb test) and surf fishing (14lb test.) Very disappointing and switched back to mono after a couple of trips.
The flourocarbon was stiffer, tangled more and came off the spool in bird nests. The heavier line for surf fishing cut the heck out of my finger.
I would not use it as a main line again - it is fine for leaders.
