Ideal tow plane pattern.
 
Establish release end of downwind @ = 3Kft or=20 so
Chop Power
Roll inverted
Pull back on stick
Deploy dive brakes
Dive for end of runway
Pull out of dive
deploy flaps
Flare and touch = down dirty
bleed off speed and stop ready to hook = up the next=20 glider.
clean up do over.
 
I realize this would give the 5 mile = final types a=20 heart attack...but it would be fun. Maybe make it a two seater so you = could=20 charge for rides ;-)
