Most options given in reply are valid. But I would like to add the use of Flap 20, provided the runway is long enough.
This gives a smoother transition to the flare and you can adopt and maintain a landing attitude whilst gently removing the power just before T/D.
Smooth, or acceptable, landings ensured EVERY TIME..
This technique is especially useful when operating at night.
When you are used to the pitch attitude and height perception just prior to touchdown, start on the Flap 30
Good luck
