I would get a Remington 870 12 gauge. I switched from a Beretta 682 to a 870 and haven't been able to tell much of a difference in my skeet scores.
That would seem to tell me that you are fortunate to have two distinctly different styles of guns that happen to fit you very decently. Typically, the dimensions on pumps and O/U's are markedly disparate that shooting both with equal aplomb is not the norm. Good for you!
As Zippy has mentioned, when utilizing the pump, MOST folks will pull the gun off the target line ever so much so as to interrupt their smooth swing on the second bird - that causes a lot of misses for most folks.
As to Tom Knapp - while he is, indeed, blessed with great hand-eye coordination - I have only seen him shoot targets that were handthrown fairly close up in the sky. Serious competition, like International trap, FITASC, Sporting, etc., typically require a fast second shot on a target that is screaming at a long distance - IF a pump was capable of winning those, competitors would be shooting them.
