i have just purchased two dvd's from MIchael Wong's Library: Weapons and Lock and Hold Security.
I'd advise anyone into the MA's to try these out as they all very professional and excellent.
Sifu Wong comes across very well and is very funny when carrying out his moves. Meaning no disrespect when i say this but what i mean is that you just know he wants to dish out the pain. Watch and you will know what i am saying.
