What else?

Benign spiral.
Cross-country aerotow (low tow in level tow and descent on tow.)
Extremely accurate, short field landing techniques, off-airport if feasible.

I teach these and more with every glider-rating checkride or flight review at Marfa.

Free checkrides: no exam fee / no glider rental fee / free room at Marfa, near the mountains of southwest Texas to March 31, 2013.
