Apparently the JDM version of the steel gray comes in a PVD finish which for me looks a ton better than the US version. I only found out after wondering why my wedges didn't look the same. A have a 50 F & a 58 K from Japan and a 54 S from the Philippines (same products offered as the US). I've yet to hear back from WedgeWorks if they can produce a custom 54 S in steel gray PVD since Japan does not offer anything else but the 54 M. Will post pictures later.
