If your footage is shaky it isn't because of "rolling shutter." It's because you are not shooting steady enough. Rolling shutter is a phenomenon where when you move a camera quickly side by side, objects (such as electrical poles, trees, etc) seem to bend and sway in the background. You said you use a cam caddie, so do I. I suggest buying a two pound velcro dumbbell to stick on the back to add a counter weight. Also, a lock out kit would help a lot.
