In the various Cessna forums I monitor, owners have reported mixed results
going to 3-blade. Some have complained of *more* vibration, though noise is
less. Something about the engine dynamic balancers, though there is
controversy about this.

Hartzell recommends replacing the lord mounts with this conversion,
according to one 210 owner who had it done.

What do the Piper owners say?
