The engine revving up faster and speeding down slower will simply not affect the aux belt system, if that was the case it'd be a problem changing down a cog, no engine accelerates faster than someone dropping it in 2nd at 35mph and dropping the clutch...
The vibration I appreciate, but XUD9s and dw8s have run with non damped crank pulleys for years, or at least a significant amount less damping than the dw10 pulley.and they use the same crankshaft. The harmonic vibrations encountered will be vastly the same.
The harmonic dampener at the end of the day is not a protection device for the aux belt, it is to stop harmonics in the crank itself, it is simply an absorbing device, I fail to believe that using one will damage the aux system.
