I used the 10" Merv Taylor Orbs Eternal for more than thirty years, and then was gifted a set of the 15" Owens rings by Jon Stetson. He thought that my 10" rings looked too small once I began using the Pop costume. The long black frock tends to make everything look smaller in my hands. I also started using thick white rope and 24" scarves for the silk to egg for the same reason.
Both of these sets were wonderful. I miss the springiness of the Merv Taylor solid rings when doing the crash link. The hollow rings are much clunkier and not as deceptive for some moves.
However, the size adds interest and makes everything seem much more amazing to the audience. I love the Owens set, and wouldn't change back.
