These are dimpled, not cross-drilled. The slotted area is also wider than usual? Not sure if I would go this route.
I can illuminate the source of your confusion... it wasn't an argument.I do not get your argument.
Cross-drilling is a '70's technology. It is usually not done right and shortens the life of the rotor.
Slots come in different shapes and sizes. Generally more aggressive shapes will wear the pads more. However, the structural integrity of the rotor is maintained.
Dimples seem to be for cosmetic use and seem somewhat tacky.
