What a score!
That design Professional is probably my favorite... I just adore the seat cluster. And used 70s Raleigh paint doesn't often come better these days.
The Mk II Super Courses have a pretty good rep around here, so if you like it and you want to have a build-a-whatever frameset, that's a good reason to keep it around. (One of the many advantages of having extra bikes!)
Of course, I would say that... I'm a Raleigh dude... I think it's hereditary.
