Heh, ye its basically similar to squash with some changes thrown in. Or to get slightly confusing its exactly like handball (the GAA/irish version - not olympic handball) with a racket.
@ BW
That sounds odd to me too, a more elastic rubber would suggest it would be more lively. But as that quote says a squash ball slows then a lot when it hits a wall or bounces while a racquetball ball continues at the same speed.
