As much as I hate turns-around-a-point, eights on pylons is the complementary maneuver. Remember that in a TAP, you must maintain a constant altitude and vary your bank to achieve a complete circle over the ground. In an eight on pylons, you maintain bank and vary your altitude to achieve a figure 8 over the ground. It helped me to tie the two maneuvers together. I used it to explain to students that struggled with the concept so that they would have something they were supposedly familiar with to start from. Of course, if they were terrible at PPL ground ref. maneuvers, you might have a bigger issue.
