dude, the best flouro is Sugoi for sure!!! $$$$ though... If you are looking for something that is abrasion resistant, straight flouro is not gonna be your cup of tea... P-line makes a hybrid flouro that is pretty dynamite, it is called flouro-clear, it casts better than any line out there, but again, not the most abrasion resistant, if you decide to give it a whirl, just check your line and re-tie.
