Judd, you mentioned an "opposite stace," if the grab was opposite hands, I imagine that the technique could have been tembinage. Was there emphasis placed on the uke's elbow? If it was opposite stance, same side grab, then it sounds like a regular kokyunage.
The main point here is to remember what you found useful from this exercise and use those aspects when your are required to teach. What was easy for you to utilize might also be easy for another.
