Comp rider here. Sound will be dull bc of Zertz inserts. Theoretically, these dampen the vibration. Theoretically.
Good news is that that seatstays asembly is essentially a rear "fork", bonded into dropouts and short tube right behind the seat. That upper joint is beautifully, unapologetically crudely finished. This "fork" is designed to be replaced if needed, instead of having entire frame less than perfect (provided parts are still being made), and that was the only thing that reconciled me with carbon in the rear. Not that I will ever race it in mud.....
Show it to the professionals and watch it carefully still.
