The OPC set has a good number of cards with poor centering. Some are easier than others.
Arguably the toughest card to find centered from any wrestling set is the King Kong Bundy from the OPC set. Hercules Hernandez is also a very tough to find centered card. Never seen one of either.
The 1982 Wrestling All Stars Series B Ray Stevens is another impossible card to find centered.
Here is my OPC set. I for the most part only collect the base cards graded and not the skits. The Bundy card has the best centering I have ever seen on one and it isn't perfect.
