I know it's not Goju or Shorin Ryu, but in both the Kenpo and JKD stuff I've done the fists tend to be kept around the ribs. If the book "Bruce Lee's Fighting Method Vol. 2" is any indication, which it my not be since for all I know it's a worthless money grab attempt, keeping the fists at the ribs would indeed be a break from the traditional hip placement.
