Thanks for the insight despite it!
If we talk about durability we also have to talk about quantity of use and intensity.
I have several bats and I am low level, so d09c lasts a year or more for me.

You can observe this even on pro level. When they loop the 1st ball on hard backspin there is often hardly a clicking sound, but the 2nd ball you can hear it.
