The S86R™ Pearl Coverstock is the strongest coverstock used on any 900 Global ball to date. The Adaptor/D™ Ceramic Asymmetric core provides 5-6″ plus of flare potential. Use the Inception™ DCT Pearl on medium-heavy lanes where a stronger shell is needed. The Inception DCT Pearl with the S86R™ coverstock is better suited to handle heavier volumes of oil than a standard pearl shell. The Adaptor/D™ Ceramic Asymmetric core represents the most efficient use of mass in any ball and provides that unique motion that only ceramic can produce. The Inception DCT Pearl gives bowlers another weapon to combat today’s modern lane oils and conditions.
