I did fly a Supr Cub for a while. For me, it didn't have the charm of the L4. I loved the minimalism of that aeroplane, the 'solo it from the back' cockpit, and its superb slow speed capability.
The Super Cub is OK, but so like so many others IMHO (including the Ciatabria). The basic Cub is just a peach!
