Bose-X,
Your preparations are certainly sensible.
I suspect that most private flyers do not make such investments or take such precautions, and therefore my original observations still stand. Your operation is quite the exception over most.
Your actions are that of risk elimination. While the possibility of a forced landing is very real, you've opened the back door, which is what risk elimination is about. I would guess you've invested in the training to use that equipment, including live water training. If so, good for you, and hopefully your example inspires others. For those who don't prepare so thoroughly, avoiding single engine flight at night, in the clouds and over water is still the sensible thing to do.
