That's the worst place to be with a heavy winter jacket with a judo specialist, and you're standing up with them. Oh, my God. Um, but I think, um, grappling, because in most self defense situations, it usually winds up with grappling. You're definitely better off, though, knowing some striking, because there's nothing more terrifying than when you go to take someone down. They actually have take down skills, but they can fight, and so they have take down defense, and they know how to fight, and then you don't know how to stand up. Like, the, the worst thing in the world is seeing someone, like, reaching who doesn't know how to do striking, and someone cracks you.
