"Trout can see both."- classic
I only use flouro for chrome... I don't care what you all say, it has been a defining factor in hooking up for pseudo steel; hook-up immediately after changing tippet from mono to flouro... too many times to be by chance.
rio powerflex to the bank for all general trout applications... def. not a need for flourocarbon, however, as others have said, it's easier to tie with, gives me a mindset which elicits confidence, and is not shredded as fast by rocks, etc. compared to mono.
with that said, I carry 3 and 4x in flouro and 0, 5, 6x in mono. Was never one for the maxima in leader building, but instead, collect my friends tapered leaders when it gets down to the point they are going to scrap it. I build off of this with the 0x in mono and taper down.
