I have assumed, perhaps incorrectly, that a payout winch *would have an
advantage. If I have 2000 ft of cable on a spool and a 6,000 ft runway,
the car with a payout winch use almost all of the *6,000ft runway length.

Were we to do a regular auto tow, the car *could only use 4,000ft of the
runway to lift the glider. A reverse pulley would also give us the full
6,000 ft but, in our case, we can't use it because of runway management
issues, not aerodynamics.
