Beach Doubles you get your hands on the ball every play, sunshine, sand between your toes (and everywhere else
), a cool (or warm) breeze to give the ball a little more action. It's also a full body workout. You burn more calories and use more muscles in 6 points on the sand courts than in an entire 6-man indoor match (to 25).
I've played indoor 6's now for well over 15 years, and after making the transition to outdoor doubles (sand), I now spend all winter long playing indoor 6's while dreaming of summer's outdoor 2's. And during the summer, I find myself fretting having to go back indoors because the summer game is so much more fun... for me.
my 2 cents.
