I would say almost every card from the set is tough to find centered. I have Randy Savage cards that have 0-100 centering and then this one posted above with 50-50.
There are a few cards that are virtually impossible to find centered but I would say generally speaking the Terry Funk and Jimmy Hart can be found with good centering. You might have to buy a bunch of cards but they are not impossible.
Here is a picture of a few Jimmy Hart cards I got signed at the Hogan's Beach Shop grand opening. I took the best Jimmy Hart OPC I had and you can see this one has strong centering,
