Yes - we change our rake for different expected wind strengths. We don't generally do much with the rudders because, at least in my case, my rudders are so neutrally balanced that the rake really doesn't affect them - I pretty much have no helm (but am working to put a little weather helm back in it). Even if I feel more or less helm, it has very little affect on boat performance so we don't mess with the rudder rake all that often.
