I was taught that (with my particular aircraft), I should always 'short field take-off'.
Particular attention being paid to air conditions ( wind speed, direction, turbulence, moisture e.t.c.), surface condition (resistance) and Bar position (centred and full-out). As soon as separation between front wheel and terrain occurs to 'nose down' and increase safety speed.
My teacher was aware that I would be almost exclusively using grass strips and warned me heavily about the dangers of moisture. He was aware of a fatality that occured due to the friction between 3 wheels, wet grass and a fence. I am unsure if there was a damp wing involved.
I intend to continue this practice as I am still here, but would love to hear any comments.
