I would suggest, that every prop manufacturer, engine maker and aviation engineer, of any standing, would support the recommendation to have your propeller dynamically balanced.
Aside from the obvious drain on the pocket, there can only be posative benefits for the propeller, engine, airframe, avionics and crew.
It would appear, from the lack of responses to my enquiry, that very few aircraft owner/maintainers are actually having this work done - I wonder why?
