My favorite is the Pawnee. I treasure the hours I spent towing and miss it horribly. What a great workhorse - tug the glider up, split S off tow, run downhill fast, spiral if you are close to the airport, and a gentle taildragger to boot. I have even flown it straight and level on three occasions. Once to break in new cylinders, once on a long aero retrieve, once flying to a contest. On the good ridge days we would fly in fierce winds, until a grownup came along and told us to knock it off. I have done a couple retrieves out of small farm strips. Much fun.
