Hello Yusshi:

When combined all of that should be helpful information in one form or another. There are at least a few experienced Gojuryu folks here. For myself I'll see what I can dig up (if anything) which might be helpful... no promises... my Goju experience is truly small indeed...

Your Hente-do does seem to have a very definate "Tensho kata" flavor to it. Are both arms closed fisted in say the mid-body height as you first begin this kata???
