You can't compare the flight dynamics from the standard MS Boeing with the real aircraft. If any real plane would be that pitch and roll sensitive as in the MS Sim, we would have a hard time flying at all

. Hmm, how could one describe that. With the aircraft, you have much more resistance with some degree of neutral movement. Just watch a real approach with a 737 once and you will see how much you can play with this yoke and how gentle the aircraft will react.
You might want to consider a 737 payware add-on program instead ? Have seen that these come a bit closer to the real thing that the regular MS aircraft.
