Loving your stuff Zwift, those knees are brutal! Your wrestling is on point!

Here's some of my stuff:
Back Throw: More or less an accident, I was turning in for a hip throw, but my posture was terrible so I wouldn't have been able to throw him over, so I turned it into this.
Half throw suplex thing: Yeah, I'm not sure which it is, but I think it's pretty cool.
Single Leg Ko Uchi (Gari): Opponent goes in for a snap kick, but my split kick allowed me to get lower and grab his kicking leg, while my kick sweeps his base leg off the floor.
What is this?: This is a confusing replay. I go for a leg grab early on, but my hand slips past his leg and grabs my opponent's shoulder. This caused his leg to be trapped inside a loop of sorts between my arm. I put him on the floor thusly, but what the heck is this thing? Max contacts tried to ruin my day, so I had to try to minimize contacts at the end.

Also, since this is partly the technique help thread, I could use some pointers on the hook technique for T3, I find it hard to avoid getting my hands grabbed. Oddly enough, usually I like having the hand grabs because I'm really good at manipulating the arms, but in this case I need some help.
