You're welcome. There's a purple belt at my school who omoplatas the **** out of me (and everyone else), so I've gotten to work on my counters to it more than my attacks with it.
You'll also be interested to know that there is also a reverse omoplata. I'm trying to find some pictures of it for you, since I suck at it too much to give a worthy explanation. I'll see if I can get my instructor to let me take some pictures of him teaching one, since I learned a fun one to do against a turtling opponent.
