the first one was the best. it was a bit stiff after you lifted off the ground, though. and you could have used the rest of the body too, not only the kicking leg. it's not really as big a problem as it could be, since if you're gonna wanna do any harder kicks than that, they simply won't do damage if you don't use the rest of the body.
the second one was stiff and symmetrical, but it was the best symmetrical decap I've ever seen. Don't get all hyped, though, the max points out of ten that a symmetrical decap can get is about two point five. and I don't even do out of ten ratings.
the last one was just sluggish grabbing and smushing of uke... a real madman would hit the spot though.
