Ok, my mistake. For some reason I thought you'd done a few years of FMA, that's why I was a bit surprised by your comment. JWT summed it up better than I could. But as he wrote, getting offline and diverting the arm. The system I do focuses on corto (close) range and medio (medium), so it's not that much different from drills and techniques we do when you're not backed up against a wall or in a corner. Take that with a bucket of salt though, I'm pretty much a newbie.
