the damage happens when jumping, the down force on the ball produces the cracks. The measels ball were direct from aramith so i don't think they are defective or counterfeit.
All i know is what i have experienced, that is the hard tips phenolic/white diamond/g-10 etc... Do damage
you can't lump the wd in with the phenolic and the g-10 tips. It's no where near that hardness.
