RM,
You misread his post. Take your head out of the dogma and pay attention.
50/50 is ok AS LONG AS you don't hang out there. When I box my weight is 50/50 because I want to move in any direction quickly--I'm also always moving. The weight shift comes when I throw a punch. Weight shifts to move are relatively minor. In thai boxing, I tend to weight the back leg more so my front leg is available for shin checks. My movement is consequently slower as I have to shift weight to move.
Bottom line--if you want to use movement as defense, you can't heavily weight one leg or you have to shift all that weight to . If you're more interested in putting body parts between you and the other guy then maybe a different distribution is necessary.
