Well, it has been my experience that is is. I am an assistant instructor at a Choylayfut kung fu school in ft. Lauderdale, Fl., and out of all my years there, and out of all the countless national and international tournaments I have been to with my school, our style has always dominated. And I'm not necessarily saying just our school, but all Choylayfut schools with reputable teachers. Wing Chung, Wah Lum, and especially Japanese styles have been unsuccesful. I'm not saying anything negative about them, they all have there good points, but when it comes to sparring they can't contend to the fast, powerful long range technique's of this style.
