In the 73 we are told to keep it on the ground for an extra second or two. Not to go back for centerline. just get straight on the runway and more speed for the ailerons(crossover on the 73) and rudder and then rudder to the floor as you rotate then find a good position for it. If your field isnt balanced then the 35 feet at the end isnt a factor. If it is you have to go on the numbers, and let the plane catch up.
