For 2 years I was GKR, after being offered a black and white belt, I felt uneasy and did some internet research, opened my mind and tried something else.
I saw the light.
With GKR it took 1 year to reach 7th Kyu, for the last year I personally refused to go to grading, as I cannot kick off one of my legs. My instructors could not fix this problem but encouraged me to grade anyway.
I still refused.
Another style fixed this problem in the first lesson.
I mean come on, they wanted me to instruct when I could not stand and balance on my left leg. Shocking
For anyone who's interested I was leaning back to far.
The comments about GKR being dangerous, oh yes it is, but only to the GKR student.
To all GKR out there, AIR DOES NOT FIGHT BACK!
And if you get into a dangerous situation RUN, RUN, RUN
