Tai-Otoshi key points:
1. Legs step to the side before stepping across to trip uke (don't stand in front of uke's hips but to the side).
2. For sleeve hand, imagine looking at your watch.
3. For lapel hand, tuck your forearm into uke's armpit
4. When you do the throw, pull uke's sleeve hand towards your left hip belt area; while pulling uke's head down towards the mat.
