"Wheelbarrowing" is for the builders.
I do not believe in slamming the nose wheel to ground, or landing on 3 wheels at once, on a nosewheel a/c. I try to "fly" the nose wheel on before I loose too much rudder and elevator control, e.g. before say, 100 kts in a heavy jet. Lets face it, above that speed the aircraft is controlled directionally, effectively by the rudder. While the nose is off the ground you DO benefit from aerodynamic braking, while wheel braking. Of that there is not doubt. On some types if you get the nose too high, on the landing roll, the elevators can become "blanketed" and elevator control can become lost.
I have used this technique on heavy jets to light a/c., in max demonstrated xwinds. On a slippery runway, the nose wheel is not much good for directional control.
Just my 2 cents worth.
