What do you guys think what riverbetsize we should use in spots like this?

With the nuts we obviously want to bet as big as possible, but at the same time we have some strong, but not nuttish hands (here e.g. AQ) which probably want to bet smaller.

Of course we could use two sizes here, but this also makes it harder to determine our bluff combinations and could leave us with difficult situations when we face a raise with a medium strong hand.
