I've had dynamic propeller balancing done on every airplane I've owned.
It's absolutely the best dollars I've ever spent on maintenance. It can
make 4-cylinder engines feel like 6-cylinder.

I have a dynamic balanance done every time my prop is R&R'ed on the plane.
Unfortunately, on my prop (a Hartzel 12v20) thats every 250 hours due to
a recurrent AD. Vibration is not your friend.
