Well if we are getting into this discussion about these signals I signal incomplete with the scissors style and not the illegal shift. However my BJ uses the illegal shift signal so I also use that under the uprights so that we look exactly the same and we look like syncronized swimmers because our arms are moving in sync.
I also use the genie signal for delay of game and I think that you also see that signal at all levels.
The one think I don't like seeing is the "I give up, don't shoot me" signal for touchdown. The signal is not palms forward with arms 30 degrees from straight up. Something like this.
(I don't have anything against this guy. I don't even know who he is.)
