The most popular Play Hybrid ball gets a 75mm release - Available in super bright UV reactive colours and with the super soft shell found on all MMX balls. MMX3 is very slightly under-filled, has a washable skin and tiny plug. If you want a large stage ball that behaves and performs like a thud this is the ball for you. The skin keeps a much rounder shape and the weight is distributed across the ball perfectly. You will also find much less weight discrepency between balls with the MMX range. Highly recommended. Price is for one ball.
