Okay, I might be able to shed a little light on this. My lineage goes back into the old Jhoon Rhee system. As a decendant of said system, my instructor's instructor (who trained under Jhoon Rhee back in the late 60's/early to mid 70's) had a special fondness for combinations and each belt level has several. Many are probably similar to what Jhoon Rhee taught each of his students (eg. blue belt #4 for our system is back leg roundhouse kick, jump tornado, spin hook kick, reverse punch; a minor change from your #3). I think that Jhoon Rhee's schools all teach the same combinations. The martial ballet, as I understand it, is more the particular forms taught to music and the forms that GM Rhee made up himself (kamsah hyung or might for right, for example) but it is not the name of Jhoon Rhee's system itself. Though I could be wrong.
