Ram Solo Skills - Rebounder Rugby Ball (Size 4) A revolutionary training ball to aid in pass development - the pass and catch Solo Skills Rugby Football Ball. One end is flat and the other a conventional rugby ball shape. The ball has been specifically developed to bounce back spin and return to the player when the flat edge is thrown or passed against a wall. See video of the ball in action on Yardgames by English Rugby Union player Freddie Burns. The Solo Skills Ball can assist players of all ages and levels in improving their passing catching and throwing skills at their own individual performance pace and independently of a training partner.
