Then don't contort. As I mentioned in another comment, insisting on keeping your fingers on the home keys is a bad idea. You should never bend the wrist while typing. When I want to hit the Ctrl key, I move my whole arm down and to the left so that my pinky (or any other finger) is over the Ctrl key. Moving your whole arm is what is recommended.
BTW, I'm not against remapping to the Caps Lock key at all - I grew up on those keyboards as well. I am merely dismayed that it is the first advice given, when it is fairly minor in preventing RSI.
