As a Shodan and junior instructor at my school, I find that when teaching the basics I have learned from my sensei, that is the best way for me. I am of average height and often find that I do not have to make adjustments on certain techniques, more so when the uke is substancially taller. I suppose that I impart my "personal style" when teaching but, I really do not pay that much attention to that. Now in the case of multiple attack Randori, all bets are off and I go on what I have learned over the years. I myself have an extreme amount more to learn and believe we are how we are taught. We should be a reflection of our teachers in some manner.
I usually recommend sticking with what you know. Remember, your "adjustments" at this point could just as easily be attributed to competency as uke... As a junior instructor, you should probably be sticking more closely to your school's curriculum and less your personal style.
