It is OK, it all depends on what you are looking for or you are going to be using it for the memory is not the great. As for leader it depends, on leader for what? I would never use it for fly line leader. I do use it on my ice fishing rods, and some of my open water fishing rods. Things you want to stay away from are like top water lures because the line sinks faster than mono and there is less stretch to it. It is a good line but keep that in mind along with what you are going to be using it for because it is not good for all applications but it is great for others.
