I've been using this defense recently (still waiting for name change by mod so sorry for the non-real name sn)
Edit: I'd also check out what Leandro Lo does w/ De La Riva Guard Passing, BJJ Scout has videos on it. Another thing I've been doing since I've seen the video a while back. Most of the matches he uses to show his defense are in the Gi for the most part, so that should help her Gi berimbolo defense.
