Add the Cessna AgWagon to the list. It is a Pawnee on steroids and has 300+HP - if you can't get air-born behind it, it wasn't meant to fly! ;-)

Actually, at the local FBO which had 2 Pawnees (235s) and one Agwagon (I think one of the early models), the Agwagon was far-and-away the least favorite. It's greatest attribute seemed to be converting fuel to noise swinging the big prop. It also seemed to want to fly faster and climb at a shallower angle than the Pawnees. Plus, it was significantly worse on fuel. As a result, it only flew on a couple of days a year when there was a ton of demand or the Pawnees were inop.

And no, it's not relevant to the question about a 1-72 :-)
