I agree leading or checking depends on the PFRer. If he is a LAG who might be raising with 9To or something and you know he'll c-bet but fold if you lead, check raising is better.

The thing is, if you check raise, keep it consistent like an overpair "see where I'm at" check raise, such as 3 times his flop bet. Sometimes LAGs think you in fact are probing and will come over the top with a draw thinking you'll fold your "weak overpair." The check/minraise line screams "I hit big, please call!"
