14 lb fireline is what I use on my striper rods. The thin diameter of the braid is great for fishing in deep water and the no-stretch line makes feeling those light hits much easier. I will usually add a 2 ft leader of 20-25 lb mono and barrel swivel to the end of the fireline. This will help reduce line twist.
On the negative side, fireline is a bit more expensive than regular mono and the braid is easy to tangle up. But with that said, it is my line of choice when fishing deep for stripers and sauger.
