PilotPete,
I was using the term CPL to indicate a commercially rated pilot. I was in no way suggesting that anybody who does this sort of flying should have an ATPL, I didn't when I did it. As far as I know our Baron is sometimes flown by a friend of Sir Mikes who does not hold a commercial licence at all.
As I said I would be happy to fly, or fly in, a piston twin in my own time but if company want to position me by air then I and my colleagues deserve the protection and performance margins that a two crew, perf A aircraft provides.
I freely admit that my opinion on the subject has changed since I was flying piston twins on passenger operations and the accident in question is main reason for that change. I have read the report and as you say they do not lay the blame at the foot of the pilot, he was in a dreadfull situation which I was lucky enough never to find myself in.
