Jake & Preston both offered you good advice. I'll add what I can. All the lines mentioned are good and you'll find fans of each.
I fish the 40 + fast intermediate and like it a lot due to the Ridge running line. I've also fished the Outbound, but didn't like it as much due to tangling issue with its thinner running line. The Outbound also has a longer 37.5' head then the Airflo's 35' head.

If you haven't cast one of the intergrated lines, do yourself a favor and visit a flyshop to cast them. They are a different animal and you won't be making a bunch of false casts with these lines.

Another option to consider is the Rio "Short" Outbound lines. These just came out. They have a 30' head and the running line has been improved from what I've heard. I plan to buy one of these and give it a try.
