2lb mono or 4lb fluorocarbon?

[FASTEDDIE29]

I had 3lb Berkeley fluoro ice on one of
My Trout set ups for 4 years! The only reason I don’t have that same set up now is because that reel exploded before the line went bad. I’m a pirate through, I use some weird stuff! Landed Trout up to 24 inches with that 3 lb test.......

I've experimented with different variations of 2-6# mono and fluro with and without leaders when targeting trout and my preferred set up is 4# Floroclear P-Line. I've found that 2# is harder to control and give me more tangles.

I caught a 12 lb carp, 23" tiger muskie, 20" pickerel and 18" largemouth bass on 2 lb fluoro without a leader this year. I believe that I get more action on 2 lb line than 4 lb test. 2 lb fluoro line without a leader is the best setup for catching small fish.
