Your time might be better served doing more JKD. My uncle helped me train for about six months so I got very little, albeit, hands-on experience. It's about your personal expression of fighting method in which body and mentality play an equal role. My uncle's 'method' was wrestling. Never took a different MA class in his life. He's just capable because he doesn't go against his personal abilities, he trains with them. He boxes his way. We beleive JKD is a concept in it's individuality of fluidity. The expression of self. If you train hard, are open minded and can or already have found your natural fighting mode, keep going with it. If you know how you fight, anything else might be superfluous except, of course, the other instructors knowledge, concepts and wisdom that just might not have occured to you. Check out burmese boxing for an adventure. Bodybuild, hit the bag, stretch and eat your wheaties. Good luck.
