This is frustrating. You're not an expert, but you make a blanket statement about "The 231 has a problem engine as far as I'm concerned." Do you mean early 231s with the -GB engine? If so, yes, there were early problems, which have been largely rectified with the -LB engines. Add an intercooler and Merlyn and it's a fantastic plane. A low time pilot can't be trained to safely operate one? Jeez, tell that to the military, which routinely teaches low time pilots to fly jets.
Sure, it only has 10 more horsepower than the J, and it isn't "...all that much faster." But by that logic, your Ovation 3 has 100 more horsepower, and isn't that much faster than my 231...in fact, maybe a bit slower.
Throughout the history of the 231, it has been discussed by armchair critics who've never actually flown them and just repeat what they've heard from early reviews of early model 231's. Maybe get some updated information on the 231 before making broad statements. Sorry for the rant...
