I have just finished three training flights in an R2160 to expand my glider aerobatic rating to cover SEP as well. I shared a video of my third flight in Private Pilot > Videos.
The Robin was a lot of fun to fly. It is easily the most responsive airplane I have ever flown. I'm looking forward to flying it more. After doing aerobatics in gliders and in the bubble canopy Robin, I just cannot imagine doing so in a Citabria or Decathalon...
That's where the airplane is now made, so no surprise there.
Personally, I'd give the Zlin a spin (pun intended) so I could add to my experience and make the "what I've flown" list one item longer.
