I never believe in one-size-fits-all sliders, because player skill plays such a big role in the game.
One thing I do to limit my own ability to roll up big numbers is use the "Ask Corso" feature - or whatever it's called now, then pick one of the plays. It prevents me from going to the well with money plays. It tends to become more of a grind-it-out game then.
I know that doesn't give you a set of sliders, but it might be an option (assuming you don't already do it) if no set of sliders seems to work for you.
