Another thing I notice is the more blatant extension and whipping motion in Bak Sing. To me this looks very ugly, slow and a good way to hyper extend your joints. I've always been taught that everything should move together. Some parts may move in front of other parts but they all move in concert. Also, not too extended or you set yourself up for a joint lock.
