What fluorocarbon line to use for trout fishing and some questions.

[fishfish1]

For the 2-4lb how is Izorline, Maxima, P-Line (what make do you recommend?), and Trilene?

Also why does it seem like 3lb test is never available? Only 2 and 4. What line do you recommend going by thin diameter, strength etc.

And what is 'memory' in fishing line?

Thanks for any help for a newbie.

I use the Berkley Vanish for leaders and mainline.. 2,4 and 6 pound..It seems to catch fish...The 6 pound I use for surf fishing also..
