I tried florocarbon line and find it too brittle and it abraids fairly easily. It just isn't worth the extra money. I echo Pwlr's feelings about it.

Line cost is something I pay attention to. I replace my Stren 4lb mono about every two usages due to line twist (with spinners). I am also always checking for abrasion in the last foot or so of line and cut my line off and retye frequently (at least every hour).

You sort of adjust to line stretch and so forth after you become familiar with a given line. Your rod choice has a lot to do with your ability to feel strikes.
