Hello Ken:

In a word, nope.

There are many perfectly fine techniques, they are not attached to any specific rankings. If it is not simple, easy and based on structure, positioning, mechanics... it is not kara-te.

Our art is kata-centric. All kinds of things are buried in plain sight. Escapes from chokes, grabs, locks... are all there.

We use the older Shorin forms prior to the creation of the Pinans, the "dai" or "sho" additions.
