tankengine,
the 180hp C150 has to be kind of "trike Super Cub", ahem. That powerful engine in that just doesn't sound right. Maybe if it was Texas C150/152 conversion to tailwheel..
Wilga, hmm. Besides recent UK publicity with Nigel Farage crash, it's good climber, designed for towing, but looks strange. Or as someone just said today at the club, corrugated cardboard box with prop.
C5, I haven't been towed by Pawnee yet as I've worked on winch training. I soloed off winch last Sunday, yesterday and today, alongside healthy dose of cable break practice. I already spend a lot on bunch of winches last six weeks. I had a ride in the back of Super Cub year ago during single seater tow, it was fun.
