Scientific Angler is your answer, most likely. Which model is dependent on what you are going to do with it. Salt Water? Tarpon? Salmon? Musky? Cold water / Cold air, Tropical Temperature?
Now if you are talking salmon Rio would also have a good floating line for that.
I think you will find S.A. has a line that is specific for each of the above species and more.
A little more information could help us help you.
