Shortly I will begin training at a Relson Gracie Jiu-jitsu school. So, since they don't teach anything with the lockdown or rubber guard, and they use the traditional half guard, and are obviously a gi school, would it be disrespectful for me to use the lockdown and some 10P techniques, or should I only use what they teach/practice? Should I save these move for the No-gi class which is only once a week?
