They Say: "The DYNAMIS is the most technically advanced ball ever produced and its unrivalled accuracy and power makes it the perfect ball to help take England to South Africa and beyond. The DYNAMIS Ball has been in development for the last 2 years and has undergone rigorous testing in both science laboratories and on football pitches by professional players from clubs across the UK and all age levels of The England team set up including the senior squad. These tests have resulted in the proof that a new 20-panel configuration is faster than the more traditional 32-panel ball thanks to the reduced curving that the new design provides."
