"2) Bruce never discarded trapping. This is a myth put forth by those who could not trap effectively and/or those who would not put in the time to be good at trapping hands. What Bruce did discard was the compound trapping aspects of HIA. According to Dan Inosanto, Bruce was special at the singular trap and hit. Several months before his death, Bruce told Wing Chun brother Hawkins Cheung that a big part of JKD was "Pak Sao and hip." Bruce would slam the opponent's elbow into their body using the bow action of the hip as a power source. As Seattle Era student Patrick Strong once said, "Bruce didn't just trap, he trapped and destroyed.""
That s right imo.
This kind of trapping was also used and teached by Larry Hartsell.
