>>21734799 feet is pretty standard for a fly rod and the length helps with Tightline presentations, mending, roll casting, taking up a little slack in the cast, and more spring on the fish to help protect light tippet, and I could probably think up a few more things that a long rod helps with. As for what you're in for,you're going to be dealing with some tangles, and frustration until you learn how to cast. Watch the orvis guide to fly fishing on youtube and also their fly casting videos. That's where I learned to cast.
