The brown belts in those days had several advanced forms from other systems to study. The later kata studies were geared to the student and often were geared to the student's capabilities. After further study how I approached black belt studies other changes were made.

The last student of our group, Paul Harper, is showing one of his prior Goju studies.

What I later developed for my group developed from these roots.
