Sometimes its the same line sometimes its not.
For years people claimed Pline Floroclear and Floroice is the same line.
Pline Floroclear 3# .16mm diameter
Pline Floroice 3# .15mm diameter
I don't know. Same line different diameter. Does that make it a different line? I think yes. Even if its the same line formula, and then the manufacturer gives it a silicon treatment, I'll say yes its different.
Most of all, it comes in a 50 yard spool. But no reel is designed to fill 50 yards, without backing to fill. Is there such a reel available that doesn't cost an arm and a leg?
