Ryu Seung Min has used many rubbers in his career, from Butterfly to Xiom. Recently I found some videos called "Ryu Seung Min Lessons" on YouTube on the channel "박PD". On these you can always see RSM, how he deals with technique, tactics and the like. However, these videos are relatively recent, so I wonder what rubbers he uses there.
