So I did this a bit last night before all hell broke loose. But I found it was pretty comparable size-wise to the EXO Seven putter I have. Obviously, shape is a bit different than that, but pure size it's close. Remember the EXO line had heads larger than the normal #7.
That may put me in the Vintage then. Ideally I'd just grab both, but that's probably not a reasonable plan. May wait to see if I can roll these at the local GG.
