Different lines for different situations. If you are using the line for lure fishing then fireline is the way to go. In fact i am usuing braid material for all my fishing these days. I just love the sesitivity and feel of the no stretch factor, fighting fish feels heaps better. I own 8lb Asso and use it as leader material and even then, to be honest, im not that thrilled by it. I prefer Sunline Basic FC for leader material. It's expensive but it's worth every cent.
If you are using the line for bait fishing it should be ok.
