Cessna Super Cub Killer

Why I switched from Super Cubs in my 30's to Sportsman STOL equipped C-170-180's.
The Cessna NACA 2412 airfoil w/ Fowler flap combined with Sportsman STOL cuff which was conceived by Marvin Davis at Lockheed Skunkworks and further developed by my father Marshall Quackenbush who sold the STC to Willie Stene is a killer combination.
