that's very interesting. That's exactly what i'm actually trying to do too, combining WC and KB. Personnaly i would go on a tan sao after the Biu sao for a better re centering and taking angle =) I would love to see some sparring in this way. Good work ! :)
Go very slowly with a drilling partner. Slow the RU-vid video down and watch what the feet are doing. Once you get the footwork and hips and body movements down then worry about the hands. The key is go slow. Also this technique works very well when your lead hand is held low. As the opponent jabs if you are in orthodox, you would twist your body to the left while blocking. Peace
