well for me sosushi or whathever he calls, is not so surprising, as babalook says, the oponents in the videos dont know how to deal with a lot of simple zwei things....like crouching the 2nd hit of 66BA and punish it......or.....using Tech Crouch hits between 4[A] and EIN hits, or keeping eating the same B+K(BE) setup with 3AA a lot of times, leting charge at maximum EIN in 4[A] withouth interrupt, etc etc........i play zwei a lot, i drop patroklos now...im just playing with zwei, and i have friends with high level play in my country, they know how to deal with all this stuff, and is a pain to win when the oponent know how to play against zwei....in online(ranked...loby) i win at least the 90% of the matches with zwei, but with my friends is 50/50 and sometimes i have more looses than wins...........but i keep saying, zwei have a lot of potential, but is a matter of time for develop a good style with him, but zwei for me is just a regular mid tier char with the tools he have, but i have very fun times playing with him ;)
pd: sorry for my bad english XD
