I see kudo as an upgraded version of Kyokushin Karate, with many judo techniques added. I'm a Blue with bar belt in Kyokushin Karate as I write this, in August 2021. Osu!
Can you train with your friends in kyokushin kudo karate? The videos of padwork and all the other kudo techniques are here on youtube. In fact it would be easier for you since Kudo came directly from Kyokushin. Its better than nothing to be self taught!
