Conversely, once slowing on the ground after a wheel landing, tail still in the air, you may run out aerodynamic control and be unable to maintain directional control at low airspeed before the tail is on the ground.
It has been my experience when flying tail wheel airplanes that wheel landings gives me better directional control during the touch down portion of the landing, if I can contact the runway with no drift and the airplane tracking straight down the runway it is far easier to keep it straight than if it starts to drift in the stall attitude just before touch down.
If it starts out going straight keeping it straight is easier than trying to correct drift produced yaw.
