Mark, I can tell your about my Leophoto LH-55. It is awesome. I purchased an Innorel 52mm first, only to return it for the lack of a damping adjustment. My method was to try each and if it did not meet my high expectations, it would be returned. My thought was I would probably end up with a RRS 55 in the end. I still have the Leo as it checked all my boxes and is very well made too. Hope this helps.
