The only issue I would have with this situation is if the CFIG asked me to go to "low tow". Is that relative to the tow pilot or me? According to the article on http://www.dg-flugzeugbau.de in "Customer Picture of the Month" - "This is no April 1st joke. It shows an aero tow of a DG-1000 - done by Alwin Guentert from Bruchsal. He is an enthusiastic aerobatic pilot and owns a suitable towing aircraft.
Please note the climbing rate of 3.5 m/sec with a speed of 170 km/h!
The air foil is totally symmetrical. So there is no difference flying "down-under".
