Change Scrolling Speed?

I like natural scrolling, but if the content moves in the same direction as my fingers, I expect it to move at the same SPEED as well. That's not the case in Lion by default, and I can't find a way to change the scrolling speed at all.

Is it hidden somewhere in Universal Access, or can you just not change it at all?

 

No, that's the speed at which your pointer moves, not scrolling, but I just figured it out (and I was right): it's hidden in Universal Access, pretty deep:



Universal Access > Mouse & Trackpad > Trackpad Options
