I think what BOAC is describing is seat of the pants flying. Not the "flies by the seat of his pants" maverick plonker but simply feeling and reacting to movement of the aircraft or merely - flying an aeroplane.

If the wing begins to lift during the take off simply use enough aileron to stop it and keep the wings level. Just like you do when you're airborne.

My old man is a test pilot and his answer to this question when I asked him a long time ago was -

A wing is designed NOT to produce lift on the ground (which is why wake vortex, a product of lift, only starts at rotation). Therefore, by using spoilers and ailerons during the take off roll you are simply increasing drag and reducing your performance margins (balanced field!). Use enough, but no more, aileron to keep the wings level should it be required and fly the aeroplane down the runway. At rotation, fly the aeroplane off the runway maintaining wings level. Do not preset roll control.

It's not verbatim but you get the idea.

For those that preset the aileron. How do you know you are not using too much?
