The only line i currently own for it is wff. I cast another guys rod out there with rio outbound short and was amazed. When I handed it back to him I said it's the only line I want to use haha. He was an older gentleman that belongs to the local fly club. Nice guy and gave me some good tips. I got interested in fly fishing a year or so ago after my son was born to be close to home. Easier to go angling 10 min away than an hour minimum. I'm liking it so far and have found some success. Just hoping to tie into a steelhead before either they're unavailable to us or what's left is a [Bleeeeep!] experience. Might as well check it off, right?
