Bill,
I started upgrading some of my sets and with a couple of them, like 1970 and 1972, I've just been going full bore trying to complete them in nice shape with well centered cards. Here's a few more of my pickups from today...and you'll notice a nod to you in the top center position...

The in-action Billy Martin and Killer cards are impossible to find centered, so I'm pretty happy with these guys, even though the Killebrew has a somewhat diamond cut.
