In any event, it is not the way to reduce deflection.
McDermott's Defy carbon-fiber-only shaft also mimics McDermott's effort to make their i-series and G-core shafts non-Revo like. Defy's carbon fiber is different from other companies's CF. As McDermott states on its website about a component in the carbon fiber rod:
SmacWrap, originally designed for the aerospace industry, absorbs vibration and dampens noise resulting in a confident hit with a soft feel and quiet sound.
OK, it is remarkable stuff, but that accomplishment of a 'confident hit' (read not a Revo hit) and quiet sound (read not a Revo tink) comes at a cost of lessening the energy transfer efficiency to the cue --- significantly. Its a sort of joke but it is an accurate test of relative energy transfer efficiency by dropping a shaft on a pool table and seeing how far it bounces. The higher the bounce, the more energy transferred. Defy doesn't bounce while other shafts do. Proof enough this CF shaft lives up to company hype that their shaft is different. But it comes with a cost of less oomph to each hit.
