The two I use most often are an Orvis CFO on my 4 weight. I like it mostly because it's got that classic look and it's light. The other one (and one I use most often) is a Hardy Lightweight on my 5 weight. Honestly the main reason I use it is because it "sounds like a Hardy". And the sound of a fish taking line off of a Hardy click-drag reel is one of the nicest sounds in the world.
