I don't know- thats the thing with judges, its all about what position you are in, in relation to them. In Kenpo, I have always been taught to snap the head around first- the body will follow. As long as you make it obvious that you are in fact looking (body posture upright, your head isnt down where your belt knot is normally) then i would say you are ok. In alot of sparring matches, spin kicks are actually encouraged because of the difficulty, and you get more points for them.
