Agree with you 100% there.
I don't keep multiple training methods. I replace the old one by a better one.
When I saw that
- TKD roundhouse kick (more detail) is better than my long fist roundhouse kick, I replaced my long fist roundhouse kick by TKD roundhouse kick.
- MT roundhouse kick (full body rotation) is better than the TKD roundhouse kick, I replaced TKD roundhouse kick by MT roundhouse kick.
The long fist system has tree kick training.
But I like the stabbing foot style pole kick training very much. The nice thing is I can train my foot sweep this way (I can't sweep up a tree trunk as in the above clip).
