Few posts ever mention this guy, who is one of my favorite martial artists.
If you notice his experience includes Judo, Karate, Ju-Jitsu and Western Boxing.
Roy was a streetfighter back in the day, and proved his Aikido worked constantly, by meeting challenges and beating people up who gave him crap.
I suggest the book "complete Aikido", which details everything he did, and why he is so great!
