When you think about it the eyes aren't that small of a target (the eye socket itself is generally 1.5 inches in diameter ) although it might be difficult to strike in hectic combat you can use it like anything else: when the oportunity presents itself. At the end of the day if you're conditioning your fingers for 5,6,7 years etc and have them extremely strong, you won't break them even if you do miss.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.
