There's fluoro and then there's fluoro "leader material". I didn't know there was a difference until recently. The fluoro "leader material" they sell is incredibly rigid and wants to spring out of your spool, so be careful with how much you put on. Personally I'm a big fan of fluoro.
This pike was caught on a whopper plopper earlier this year. It was wavy, cloudy but I was antsy to try it out and got this baby on my 2nd cast.
