My upper lip is permanently misshapen (altho subtly) because I got smacked in the face with a racket years ago (it was either squash or racketball, can't remember).

I'd say racketball's a fairly unique racket sport in which you spend huge amounts of attention to rebounding, angles, and dancing around the opponent. I agree that it can be tonnes of fun at the best of times. Unfortunately, the fact that both players are operating in the same space makes it far less workable to me than tennis, table-tennis, badminton, etc. So many opportunities for gamesmanship, racket-injury, etc.

Anyway, to @[email protected], my take is that racketball & squash both require specialised, wooden-lined courts that are probably more expensive to build, with less candidate locations, than the other racket sports. With TT for example, you can literally fold up the 'court' and wheel a couple of them in to a big closet, by comparison.
