I will throw my hat in on this one. I have areas that have already been discussed that I would address. Assuming that the alignment specs are equal on both sides and the thrust angle is correct. things that can cause your pull are.

1. Brake pull, sticking brake caliper, usually will not pull when brakes are applied.
2. Binding steering rack.
3. Tires, Easy to diagnose by swapping front tires from one side to another.
4. Tight ball joint.

I am assuming that that the pull was not there before the work was done so I am not to concerd about the above items. Do not get to excited about alignment specs, as long as they are equal on both sides the car should not pull.

My guess would be a corner balance issue and or control arm bushing indexing. Your mechanic is incorrect regarding corner balance. Also If the bushing were indexed incorrectly it can cause binding of the control arm that can dramatically effect corner balance. The car will never be right with this problem and the bushings will fail prematurely because of stress on the bushings. In the rested state without the struts attached the lower control arms should be close to the natural ride hight.

All the above items are easy to diagnose, and they each need to be eliminated one at a time to correct the problum.
