The Ion series has been developed in collaboration with multiple British Open Champion David Palmer, and the Ion Storm was used for his 2008 British Open victory. The Ion racquets use Nano-Crystalline Technology (NCT) as an additive to the polymer structure of the graphite frame, for reinforcement at key stress points while allowing for finetuning of the weight and balance. The combination of NCT with the Ion frame geometry also effectively reduces frame distortion and torque for a larger sweetspot and greater control for hard hitters such as Palmer. The shaft is flared in 2 dimensions between the bridge and the handle to create a progressive flex, increasing power transfer.
