Hi there.
Hmm… this will be gentle by my reckoning… so take it as it is…
Okay. The obvious question (as brought up by Buka) is what you're currently training for "self defence", and why you think it's not sufficient? That can lead us into all kinds of interesting areas regarding what self defence actually is, what the requirements really are (physically and combatively, much less is needed than most think), but we'll start with what your actual training background (past and current) is.
Er… okay… and exactly how did you come to that conclusion? I mean, I'm assuming you're then ruling out the sutemi waza, ne waza and so forth, yeah? Including the katame no kata that was one of the very first formalised kata sets that Kano came up with to teach his art? And how does Judo's throwing methods then differ from any other throwing art's methods? Are other arts only able to throw someone so they're kneeling? Or still standing themselves?
Yeah… getting back to what "self defence" actually is… head kicks are largely frowned upon, so… maybe get out of that headspace?
Good question, considering the impression you have so far…
Judo-ka wear tough gi so they don't rip their work shirts in practice. In an actual application, of course, you'd likely be unconcerned with the state of the other guys clothing. For the record, though, the clothing has no real bearing on "leverage" or "torque" in throwing arts… my arts range from being able to throw someone in armour through to a light t-shirt/no shirt at all…
Being that close to anyone (in a combative situation/fight) can see you punched in the face… but a proper judo kumi-te grip is actually pretty good defence against being hit. You're controlling both sides of the opponent (both arms), and have quite a good amount of sensitivity built in to "feel" what your opponent is doing and where they're moving.
Frankly, good luck elbowing me from a proper grip. On the other hand, elbowing the guy I'm about to throw… that's relatively easy (in other words, you seem rather unaware of the actual position of the arms here, on both sides… of course, judo-ka train to work with their personally preferred grips, so there's no single grip you can define as the only one used in Judo…).
Okay….
So… one of the reasons you're "skeptical" about Judo is that "nowadays (it's) more of a sport than self-defence", but you then look to kickboxing (which is purely a sporting competitive format), muay Thai (a competitive sporting system) and Sanshou/Sanda (a competitive form of Chinese kickboxing) as examples for something better… and then look to them for takedown and throwing methods, even though they are all primarily striking systems with some rudimentary takedowns at best (none in most forms of kickboxing at all)?
And again, you know all of this based on… what? What experience with BJJ do you have to say it's "silly" for self defence? How are you able to assess the vulnerability of two of the most stable and safest positions (in the context of ground work… which also features pretty well in Judo, by the way… I mean… you are aware of where BJJ comes from, yeah?) in ground fighting? Or the viability of what are honestly pretty decent actions in the clip you posted?
I'll be honest. What I think is that you have no experience with Judo… no experience with BJJ… no experience with much of the realities of fighting, self defence, and more… but, based on what you think you know (which isn't much), you've made up your own mind already. So, let's take it back a step or three.
You mention that you are looking to "round out your game for self defence"… okay. What exactly are you looking for? Why were you looking at Judo in the first place? Once we look at that, then we might be able to get somewhere… but right now, you're already convinced of what you think you know, and have reasoned your way to whatever conclusion you had come up with. And that means you'll have two options… either continue to believe what you think you know, and justify your perceptions the way you have… in which case nothing we say can or will change that… or you recognise that you're coming from a position where you're not quite really in a position to make such an assessment, and we can look at what might suit you best.
