Many Judo-do throws have unusual names like: The Climbing Plant, The Twins, and The Blessed Earth. While some Judo-do throws can be identified as variations of Judo throws, others are based on quite different principles. For example, several throws use the idea of initially sacrificing one's balance, but then regaining it by pulling against the opponent as his or her body passes the thrower, with both actions accelerating the opponent.
When Fleck passed away, the system was inherited by Professor Wally Strauss in Australia. Inheritance passed back to Europe when Strauss died in 1987. Teaching of Judo-do is now largely limited to Austria, Germany and Australia.
