Long time no see...how are you? All of these lines are rated quite a bit above 2# test. I just had my knee replaced or I would go look at diameter. I have a 20,000 yard spool of it. I have even gone the Stroft...Tectan route but always come back to the SOS....when I use mono. It is a little bigger than P Line Cx Premium but I find it casts just as far...better knot strength. Pretty much my same findings as the other lines mentioned. But my main line is now the hi-vis chartreuse NanoFil. I just can't see any 2# test at all anymore unless it is hi-vis. I will use a fluro leader with it. These old eyes are failing me disco.
