I've completely moved on to C-m instead of RET and C-h instead of Backspace. I did this after feeling some stress on my right pinky (it would twitch involuntary when I laid in bed after a long coding day,) on which occasion I also switched from Dvorak to Programmer Dvorak (sharing the load from typing square brackets and curly braces among other fingers.) My left pinky, on the other hand, didn't suffer much because Caps Lock was already remapped to Ctrl.
