I realize some believe this is strictly a matter of personal choice and others believe there is in fact a right and wrong answer to the question of whether it's proper form to use your dive suit for buoyancy control.
Though I'm too new to the sport to speak with any authority on the subject, I found this short article which, in my view, makes a pretty good case against using the dive suit for bc. http://www.baue.org/faq/dynamic_instability.html
Essentially, the article briefly explains the concept of dynamic instability, and then points out how the two ideas of being weighted properly and not using your drysuit for buoyancy control help to minimize the potential for dynamic instability.
