The best BJJ takedowns?

[darkyellowsky]

I was wondering what was the most commonly used takedown in a BJJ competition? Single leg takedown, double leg takedown, hip or shoulder throws, or sweeps.

My faves are a single leg and... (looking at http://judoinfo.com)... "Harai Tsuri Komi Ashi" and "Osoto Gari".

At the BJJ tournaments I've been to I haven't seen that many throws or clean takedowns, but I haven't been to that many so I can't contribute much. In terms of no-gi (submission wrestling), I love to tackle. Tani otoshi (valley drop) is one of my favorite judo throws in terms of high percentage success.
