starting from a double wrist grab is fairly bogus indeed. the principals of the throw i think do rely on your opponent breaking his own ballance for the sake of holding on to your wrists, so it might be a bad application as it stands in the video, however the guys who posted it did not intend it to be one for that move.
im in the "i'd rather hit then throw" boat as well, maybe if it was modifyed a bit. like the low hand grabs the wrist or sleve of the opponent and drags it down and back on an angle and the "over the top" handcould srtike, and the follow through of the shoulder shove them back into a throw?
i think a forum member posted a video application of this move somewhere on the boards, i'll look for it and see if it would fit better then what i've already put up.
its not supposed to make sense
