wrist cutting is a viable technique. Even in staff techniques, the goal is to strike the wrist, whether in a direct strike, or to slide down the opponent's weapon and strike the wrist, then the next strike is to the head or torso. "When using the staff, don't expect two sounds," is an old adage. There should never be "clack" "Clack" "Clack" back and forth in true fighting. That is for two-man sets, which are for demo purposes and are basically useless for teaching real skill, other than "clack" "clack". You strike the hand/wrist, the weapon drops.
The other thing is that gim techniques are at a higher level than the dao, which in turn raises your skill level.
But I am in agreement with the uselessness of the flower techniques.
My Sifu taught me a Southern "Village," gim set that is devoid of flower technique. There is no walking around, spinning, prancing techniques. Only parrying and cutting. It's no crowd pleaser, but it gets the job done.
