I'm not usually one to make the argument of the preservationist, but in this case I will. The Superior is a relatively rare frame, and to have found one NOS is even more rare. From a collector's viewpoint, I think it would be a shame to modify and respray an NOS frame.

I might understand if there is some outstanding element in ride quality and sizing that can't be found in other available frames, and you want to modernize it...but it's NOS!

Okay, enough preaching. It's your frameset, it's America. Have at it.
