I have also mapped the capslock key to super, but FWIW I've had a lot less trouble hitting the actual super key ever since I started using my ring finger for it (I used to use, and see most people using either pinky or palm, both of which require moving the hand quite a bit).

Depends on the placement and size of the standard super key on your keyboard. Some keyboards make it quite small.
