So far I'm the only person who's marked other, so I think I should probably elaborate on mine.
Japanese Jiu-Jitsu and Aikido almost always start on the feet, so we actually practice using the submissions as takedowns. Sub-Takedowns are awesome, my personal favorite is the standing armbar to BJJ style shoulder snapper (reminiscent of the submission that Ed Herman threw on Danny 2 weeks ago on TUF).
Sometimes it's just easier to make them tap standing, but if I had to pick from on on your list I'd go with the "Japanese whizzer" (do people really use this term) a rush + shoulder toss + torque in the hips = opponent is one their back plus I'm passed their guard.
