Spalding in the range is the ball used for outdoor / outdoor. I strongly advise players to move towards hybrid balloons indoor / outdoor. On the one hand the price is higher (25) and rebounds are bad. So he must inflate them to play with.
However, the SILVER model is just outstanding. I've had more than a year ... I play regularly and grip only beginning to hang less. The ball was used in winter and summer, on concrete, covering city etc. The reference!
