The most advanced line of blanks in the world... CENTURY. What sets them apart from other blanks is the special blend of epoxy resin, the finest grade of carbon fiber, and their AUTOCLAVE process. During the curing stage of the blank, the autoclave process is able to keep total control of pressure and temperature. That leaves a void free composite with only enough resin to hold the carbon together. That in turn makes the blank less brittle, have a better recovery, longer life, and provides the longest possible cast!
