i have two sets of wheels. i can feel a difference when i have the lighter wheel on the rear, not as much on the front. my bike is fixed wheel and before i take off i lift the rear up by the seat so i can rotate the pedal around to the spot i like. even doing this there is a noticeable difference in which wheel is easier to accelerate. same gearing on each wheel. dura ace hb7600/open pro vs. campy record pista/saavedra turbo.
