check out this video: http://www.youtube.com/watch?v=cFksJ7sLPn0 ball badminton doesnt seem to have long rallies like in badminton though.
ball badminton has been around for a while....... played outdoors on mud courts with teams of 6 players a side(or is it 5 i forget) largely in schools and colleges in India and the subcontinent. fun sport but does not have the pace and action of badminton. best enjoyed when you play the game for yourself..
