what is your favorite kicking combination on taekwondo?

I don't taekwondo, but my daughter does and her favorite is just a couple of double sidekicks, followed by an axe to the head. She loves taekwondo dearly and is currently working on perfecting a 360 degree spinning kick, like Mark Lopez demonstrated on the Today show. It's amazing how fast it's done. She just completed part 2 of a three part black belt test, so hopefully she will have her Kukkiwon certification by the end of this year. Good luck!
