Arrrr... the joys of technological advancement!
There is a problem with elastomeric dampers as well. The elastomeric elements must be within 5% of each other relative to their compressibility and tensile capabilities. If they are not you can get into a condition called air resonance, which is as bad as ground resonance. This same condition can manifest itself on rotorheads with hydraulic dampers.
