Ha, this is what I love about bike forums, depending on the forum, totally different philosophies. On mechanic forum, definitely a "that it works is what matters" philosophy. On C&V, "making it 'right'" is paramount. Dont even get me started on different sensibilities between road forum and mountain bike forum.
OK, but you are still considering using Campy cups with the Sun Tour spindle so that can't be "right" either. Restorations are works of love, not common sense aren't they?
