David, yours was an epic achievement mate! I've heard tell of your trip and have seen the website. Route is very similar.
Big advantage of the flexwing vs the Cherokee I think is that despite being slower, I believe it uses MoGas, and for us only being able tomplan to stop where we can find Avgas is a huge limitation!
I'd love to hear what weather you struck - we're going at different ends of the year, but I'll be you struck some convective weather?
PM me and let's exchange email details...
Andy
