I'm not arguing with you craze. If you could hear me say the words instead of just reading them, you would hear a nice relaxed tone and it would all be said with a smile.

If anything, I'm curious about your technique and open minded in case you actually do know better. If you want, i can send you a video of myself punching to demonstrate what i mean. I've long since considered my punching technique one of, if not my greatest skill.
Anyway, i DO understand what you mean by the punch returning before it is fully extended, in that the full power of the punch can be felt at any distance as long as it is coming directly off your body, like a flywheel. It's just that i've read so many books and articles in punching, and i've yet to come across anything saying that the full extension should never be used.
The reason i said that we should agree to disagree, is because everytime i've repeatedly expressed a strong opinion, a moderator has closed the thread, even though i felt that i had more to say. Once again, this is to be read in a relaxed and calm tone, and is not a jab at any moderator. After all they obviously know their stuff

My opinions may be strong at times, but they are never said in anger or frustration.

I am genuinely interested in what you have to say, but i would also like to hear what the other experienced MAists have to say on this issue.

And here's something to contradict everything i've just said

go and visit a class. my brother and i did and we wre hooked after 10 minutes. we also attended classes given by a instuctor certified by paul vunak and for injuries expect sore wrists shins, elbows, forearms etc... but it's nothing you can't handle don't be afraid go in without regards for yourself and you be fine

hmmm interesting thread. I've been reading the posts. I might add though that any martial art or physical form of conditioning their's always that "what if" of being injured, the chance your taking. As far as your concern goes I'd recommened wrist streghthening, such as wrist curls on a dumbbell or isometric wrist stregthening. Jeet Kune Do like any other form of combative training is gonna be physical and injuries are always a possibility. On the street your gonna get injured if you get into a fight. Even if it is one bruise.
