I really believe it matters a lot how he perceives you and your lines.. and how thin he can value bet the river.
I think standard is a smallish blocking bet on the river but c/r has it's merits if you have c/r the river frequently..
I also believe that he will call with more hands than he will valuebet with so c/r gains most of its value from pure bluffs
but I am not sure how often he is going to the river with air so this is mostly a hand that would pay off anyways
but might not always value bet the river.
Furthermore I doubt he calls the c/r often enough with hands that he would raise the river with so all combined I prefer bet/call without specific images..
