That's what my thread was all about: biu SAO is a good block. Biu JEE is a useless attack...again, in MY opinion. There is only so much conditioning that can be done for the fingers. At the end of the day, they are still far too easy to break or sprain for me to try doing a finger jab to the eyes. Think about it: the vulnerable areas on the body are mostly very small targets. Example: the eyes. The ability to hit a small target when under stress (example: being attacked) are severely diminished. Therefore, in my opinion biu jee is one of the most useless attacks in the Wing Chun arsenal.
