The powder blue jersey was very cool, but they dropped the bolt on the pant leg when they brought that in:

I think I'd go with the '61-'63 version for the total package...gold bolts, pant bolts, helmet number. I give this one an edge over the '60 version because the numbers would have been more easily readable from a distance or on TV.
In context, the unis fit the playing style...wide open offense, plenty of speed...just as the simple Big G fit the Lombardi style...execution and physicality over complexity.
