Actually, a real emphasis on "stronger and deeper" does not have much to do with Shuri-te at all. I dont know if Azato's karate should really even be counted. Azato didn't contribute much to the development of Shotokan, since the first chance Azato had to get rid of Funakoshi he did and passed him off to Itosu. Personally I think Itosu had more impact that Azato. Sadly even Kenwa Mabuni had more impact on the development of Shotokan that Azato. Tomo
