The CAD designed rocker, moves all the weight to the center, reducing the amount rotating weight. Also the rockers are stronger, making them more stable at higher RPM. Ratios vary from 1.52 to 1.7. Not only do they look trick, but they'll rev at the higher RPM with a lower "effective" weight on the valve.
