Hmmmmmm I was actually talking about a straight up armbar+toss, without hooking the leg, which has the option to transition to mount if you can't secure the spiderweb/armbar, from a pretty basic set up. Also, I thought you meant that you had to have the posture fully broken; about halfway broken seems to be fairly doable, at least in my brief bit of experience.
You girls at West La are who inspired me to try to get this into my game, Jee. You all seem to love armbars more than I do, and I really love armbars. Just suck at getting them from guard.
Perfect example of what I mean is at the 1:20 mark
