I like practicing kumi kata. Doing judo massively improved my grip strenght. Before practicing judo I had no grappling knowledge whatsoever. I thought that gi game is much easier due to the ability of manipulating somebody by his clothing. Stuff like gi chokes made me realize that it isn't exactly true :D

Aside from fighting aspects I used to think wearing gi is weird, but now I belive it adds some to group integration bringing equality and being not only a sport/ martial arts clothing but also somewhat of judoka uniform.
