they are not similar to kamiko's ones, the first 2 are ok, the 3rd and 4th are not that good. However, i made only 1 backflip helico wich works kinda well, i think it's the most difficult kind of move u can try to make. I'm still trying to invent a backflip helico which reaches uke in the 3rd turn, only kamiko did it atm. We can help each other if u want
