They say the danger of loading up the aircraft in the turn to final outweighs the advantage of being in a position to land from three out of four pattern legs. They say student pilots might land too long and run off the approach end of the runway. Those points are well taken, but they are wrong for several reasons. Foremost, it acquaints pilots with the abilities and limitations of their aircraft. Second, the effects of surface wind are more apparent with a cropped, high pattern.
Pilots can then learn to use wind to their advantage.
Obstacle clearance is another advantage. Use the speeds in the owners manual and remember to adjust them for operating weight, as permitted. Don't waste a knot climbing out. During takeoff leg, a pilot's brain should be spring-loaded to engine failure. Precious few individuals are flying rocketships with the surplus power needed to make a takeoff leg turnaround possible.
