We did touch-and-goīs while on tow occasionally to get current again and to practise a malfunctioning hook. Using the airbrakes is perfectly fine as long as you donīt slam them out.
When on vacation in Hungary we would always do low tows behind the Wilga. That was the way they did it there. On cross country flights itīs so much less exhausting, you can hardly loose sight of the towplane, especially as the instructor.
