Kundalini Teacher Training

Hi! I was practising Kundalini Yoga for around one week now and I love it so much that I decided to do a Kundalini Teacher Training as soon as possible. In my yoga studio it was the Kundalini Style taught by Yogi Bhajan. I found a yoga school in India that teach Kundalini in the traditional way (not taught by Yogi Bhajan). Does anyone know if there is a big difference between these two styles?? I made internet research and didn’t find very useful answers. The Style of Yogi Bhajan should be the more westernized form. Does it make sense to do the Kundalini teacher training in the traditional way if my aim is to teach it in Europe (Germany)? Appreciate your answers very much.
