(Why? We fly from a short runway, surrounded by houses
and trees, and
we have modern, low drag gliders rather than 2-33s.
For us, this is a
chancy maneuver with an experienced instructor in back,
and clearly
dangerous to send solo students off to practice it
on their own.)

What is the length of your runway?
Why is it a chancy maneuver with an experienced instructor
in back?
Do your instructors send solo students off to practice
rope breaks on their own?
