I have a 2008. If anything regarding the forks changed between 2008 and 2011, it was hardly significant. I agree, the forks are harsh over abrupt bumps, i.e. expansion joints, RR crossings, frost heaves and cracks, surface transitions. That's the high speed compression damping. With stock springs and oil weight, rebound valving is pretty close. The accurate method of adjustment for the harsh high speed compression damping is the changing of valving shim thickness or stack height. As you experienced, oil weight affects rebound as well, when you really didn't want to. I prefer to use straight rate springs as progressive springs a difficult to valve damping for. They're more of a compromise for riders who have gross weight swings like passengers and heavy luggage.
Bottoming out is ultimately the spring rate. Bottoming can be resisted internally be varying oil height (though you can still hydraulic bottom if springs are too soft), and adjusting low speed and high speed compression valving. If I were bottoming either the front or back on high speed compression bumps, I'd immediately change my springs.
The best ride you know is the best you've ever ridden. I've ridden many better. Like your levers, suspension is meant to be customized. Mine rarely remains stock for long.
