Assuming the aerotow release procedure is still the same these days i.e after waving off the glider or the glider releases early, the tug descends down and to the right while the glider goes up and left.
Our procedure many years ago during the release was to reduce to 2000rpm and increase the break away turn to 60 degrees of bank, once the ROD started increasing then control it with back pressure on the stick increasing the "g" loading and the ROD, this would produce around a 2500 fpm ROD while keeping the engine warm with the CHT in the green all the time, then at a suitable altitude usually around 500ft stop the turn heading directly for the airfield for a low circuit slowly reducing power as required.
Lookout was maintained and good out of the overhead cockpit windows on the Cub during the steep descending turn, and of course tow times were quick because the descent from the average tow altitude 2500ft to landing was around 2 minutes.
