The Palladium set (Green 6 + Brown 7) is the new one that the JPBA (pro org) use, and the Platinum (Gray 6 + Cyan(?) 7) is the one that JAPA (amateur org) use. It gets quite confusingThere are a couple of sets with different colour patterns. The Japanese version of the platinum set is used by one of the big hall franchises in the city. Every time I go there I seem to get confused. All sixes and sevens to me... Literally, need to stop and ask myself is this the 6 or the 7It's cost me money a few times.
