PW, A useful technique but needs practice to turn with power in a taildragger and you have to be constantly assessing the wind. In addition to the kinetic energy gain you can sometimes get another gain because you are starting the take-off run with a higher prop efficiency. With some fixed-pitch props part of the prop will be stalled at max static rpm with the aircraft stationary. When this happens, the thrust will increase as the aircraft initially accelerates.
This technique also of necessity prevents you using every foot of the available distance because your radius of turn is larger at higher speed. It is therefore worth assessing if the shape of the field gives a better result by positioning the aircraft tail right back in the far corner of the field. On occasions I have not been too proud to get out of my aircraft and push the tail right back to the hedge. I like to have as big a margin as I can, in case something doesn't go to plan.
