I was wondering, I have heard of some aikido dojos where no level proof is carried out, nor are there any grades i.e. there is no kyu structure/advancement.
The dojo practitioners either have a white belt and normal gi, or the black trousers one, and sessions are divided in "beginners" and "advanced" ones.
Are there any pros and cons for this system, in your opinion? (apart from not being able to feel cocky at the idea of reaching 1st dan one day
