this is pretty cool i'm learning stuff about judo i didn't even know in this forum, however i think and this is only my opionion saying a particular move is common is slightly untrue because judo has eveolved since it left japan and every country has style of doing certain things differently. i rember a little while ago i went to a seminar to see a high level japanese jujitsu practitioner his name is O'Sensei Alexey Kunin and one of the things we was talking to us about is why there are so many different styles of jujitsu and how they mirror the strengths and weaknesses of the person created it, modified it, etc, and i believe this is the same for judo or any other martial art alot of most peoples style is based on their instructors style which goes on and on. so if a person start a new club if their ot so good a certain things they wont teach them as much and over time they might not get taught at all.
anyway thats just my hypothesis on why i haven't see this move in judo, if you don;t agree thats your prerogative, and if you have evidence to the contrary post it i'm more than willing to listen well read but you get what i mean.
