Both my wife and I roll on 20s daily, I can not remember the last time I was not on 20s, and shes been on 20s for four years now, not a single bend or pop, depends on cast wheels or forged, people always hear about their buddies cheap cast wheels cracking or bending, you will not hear too much about forged wheels getting hurt.
Rock chips you have to deal with, they come maybe once every few years for me.
