I could be wrong, but perhaps the reason that most people don't stick with kung fu is they that don't advance it far enough. With kung fu, you've got twice as many things to attack with (2 legs and 2 arms) and you've got the chance of making a lethal blow. with weapons, you've only got 2. anyway, the place where the two balance out is that with kung fu you'll be making more attacks at once.
