Case Clinger is the purest racer I've seen. In any sort of national race where tactics come into play, that dude has the close to beat anybody. I think if they were in a tactical 5k, Clinger could change gears faster than Hunter. People will say that Hunter will easily win in an overall fast race, but I think Clinger has a strength that many don't know about. It would be tighter than ppl think.
Just my two cents, from a guy that's seen a lot of Casey's races.
