The wave track still has a torque bias. If one tire is spinning the other tire will get 3 times the torque applied to the slipping tire assuming it setup to 3:1. THE one advantage of the wavetrack is when one tire gets zero applied torque then the other gets 100%.
I personally love my detroit locker. FYI, circle track lockers are unique and not a good comparison to an off the shelf locker from eaton.
