i think most indoor events now are on hardcourt, not too many on carpet but i'm not certain on that. carpet the ball stays low so maybe someone who is pretty good on grass should do decent on carpet. counter punchers probably do a bit better as well, as mentioned about myskina taking it on the rise, using the opponents power and pace off the court to help get a little bit extra on it.
