It sounds like you had a bad batch of 2lb line. If I break more than once or twice in a short period of time that line is getting thrown away and re-spooled with some new line. I have always like the 3lb Pline, I use that for my perch rods and panfish rods as well. Floro has its time and place, most places I fish you can get by with standard line, however sometimes a finicky bite will require florocarbon. Most reels come with a back up spool, try one with florocarbon switch up spools and let the fish tell you what they prefer.
Its going to be a long 3.5 more months before ice season…but it will be here soon enough.
