I'm sure that's all true, Dusty, but doing a good dynamic balance job on an Ivo with the small spinner seems very difficult if not impossible for a guy with a DynaVibe or any dynamic balancer. I've very rarely seen a propeller that has been well-balanced statically that couldn't benefit (sometimes greatly) from a dynamic balancing job. Since the entire rotating assembly is being balanced, the needed weight is most often not even in line with the propeller blades. At least that's been my experience.
