I am a green belt who has been doing Judo for two plus years (off and on when time allows) My favorite throws are ippon seionage, o soto gari, o uchi gari, and tai otoshi, but I don't use all very effectively. I also love uchi mata, harai goshi, and susai tsurkomi goshi, but I am definitely not great at these. I like to try and combo o uchi to o soto, and ko soto to tai otoshi/harai.
I started Judo at 30. I just got off an army deployment where we practissed unorganized grappling. When I got home I didn't have any partners, so I wrestled with my dog until he almost bit my ear off (literally). I then tried out Judo without really knowing what it was, b/c it was near my house. I have really enjoyed it since then.
