nope, don't agree.  my ur-q with open diffs could be a real handful when punting hard.  locking the centre diff solved the problem but didn't make the car nearly as responsive as my s2 with it's torsen (less understeer).

in addition the speed that the torsen reacts to changing surface conditions is much quicker than your ability to turn the diff lock!

in addition, the torsen puts more torque to the driven wheels (up to 75%) versus 50% with a locked centre diff.
