On the contrary, I think that the JKD school could teach you "the real deal" when it comes to trapping, but it just won't be as complex a system as it is in Wing Chun. It will still serve you well. Wing Chun is not complex...it all depends on who you learn from and how much patience you have. It can be learned in a relatively short period of time if you have a good sifu. Bad Sifu's stretch it out and make it more complex than it has to be.
