Hi there
For touring and aeros, an RV-7 with a fuel injected engine (you can even use a fixed-pitch prop and a carb'd engine, if you want). Compared to the two types you have short-listed, it's much, much cheaper to run and keep. They have been well proven as fast long-range tourers, support is excellent and the internet groups provide a huge network of information on keeping them running. Why not look up Gerry Humphrey's EI-HUM on YooToob, as proof?
