I cant decide which one I prefer.

Co-Polymer should be listed as well and that gets my vote

Limiting your choices in bass fishing will limit your success in the long run.

Monofilament is great for crankbaits, jerkbaits, and spinnerbaits due to the line stretch that gives the lures a little extra bite when you set the hook. It helps to delay your reaction so you don't pull the lure away from the fish before it can fully engulf the lure.

Flourocarbon has very little stretch and a much better amout of sensitivity than monofilament.  It is best suited for finesse presentations.  Worms, jigs, tubes etc....

Braid is a tough line with no stretch and more sensativity than flourocarbon.  It is best used for fishing heavy cover such as thick pads, or weeds with jigs and most popularly, frogs.

As stated above.  I think they both have their place and can be used as needed.

Overall, I would say I use fluorocarbon more so than mono but I prefer copolomyer lines above anything else.

Another vote for co-polymer.  I use nothing but Silver Thread.

I've been using Seagaur InvisX this year, and I'll never go back to Trilene. I used to use nothing but Trilene Sensation until last year, where it seemed like every spool I got was bad.

I prefer braid.  

However, I think each line has its place for various applications.
