Very true. And the 711 (my holy grail putter) is even harder to find!! I like the uniqueness of the 7xx line - not quite a rounded bumper but not quite a flat bumper style either.
Fharbist, that Blue oil 007 is so nice( seems you have a very uniform Blue Oil finish/hues all around on that particular putter, which is great!)...congrats on the fine collection you have..
