The ATSB did a report on a Glasair that came to grief in Brisbane many years ago. what they found is that private pilots who have been flying Cessnas and Pipers for most of their life splash out and get themselves a high performance machine and are suddenly in a world of aviation they are not used to. Light control inputs and high stall speeds. Maybe some money spent on additional training to come to terms with the differences would be well spent. A bit like the MU-2. Once private pilots did the FS course on them the accident rate came down.
