I was just getting ready to start a new thread about this rod to see if anyone cast it yet. It's Scott's new fast-action rod that will replace the S4 and is supposed to compete against/be an alternative to the Sage One. I believe they are targeting medium-fast action guys looking for a fast action to throw bigger bugs and cut through the wind. It just one "best new freshwater fly rod" and "best of show" at this year's IFTD show a few weeks ago. A number of the magazines have done short articles on it and they really like it FWIW. This one has a link to an interview and video.
I really want to cast one in 6 wt.
