Right about losing airspeed for the priviledge of landing in small places.My supercub once cruised about 108 mph with a 160 hp.I have since added a cubcrafters 180 hp conversion,extended wings,drooping ailerons(like robertson stol),vortex generators,extended ailerons,bigger tires and a few other things.Now i cruise about 90 mph.I have had lots of go fast planes,but the stol ones are neat,nothing like being able to land almost anywhere.Probably in some parts of the country this isnt real important,but in the woods it is nice.Those fast ones were fun,but had to drive 50 miles to go flying,now just walk across the road.
