5 club 4-count (async)
A starts with 3 clubs and throws diagonal passes, B starts with 2 clubs and throws straight passes.
B reacts on an incoming pass as late as comfortably possible with self, self, pass, then waits for the next pass.
A reacts the same way on the incoming pass from B.
Additional Things to Do
There is a 4 beats pause after each pass until you have to react to the next one. There is time for either "self zip self zip".
