Also for cruise you may have to adjust the pitch angle of the horizontal stab - or fly with a bit of nose up trim. You may find it necessary to adjust your elevator trim more frequently (than what?) to compensate for different thrust/power levels of the engine. But, since once at cruise we tend to leave the power setting set- probably not much of a bother.
