lol, clicked your sig links, you really are Ivaylo Ivanov! Just not the one I thought. I thought it was a more unique name.
https://en.wikipedia.org/wiki/Ivaylo_Ivanov_(judoka)
Ivaylo Ivanov would be one of the most popular names in Bulgaria
Ivaylo was a national hero, similar to William Wallace.
Ivanov would be as spread family name, as is Smith.
Also, naming traditions in Bulgaria are the reason, if your family name is Ivanov, its very likely to have Ivan, Ivaylo or similar, as a first name.
Hence, the usual confusion with my younger countryman with the same name
I am also a Judo guy (and Sambo, and BJJ, and a Wrestling guy) but my Judo accomplishments are more humble.
Experience though, is entirely different matter.
Because I spent the last 20 years living, training and working in Japan, China, Mexico and Brazil.
Never stopped training.
Visited hundreds of gyms, including ones in USA.
So, I can safely say, when I express an opinion here, is not based on observation in 2 gyms, practicing one sport, for the last 3 years.
Sorry for the off topic
