Hmm...interesting post. I would when doing Aero's, without a doubt. You've got me thining now, what about on "normal" trips? Doesn't sound like a bad idea, you never know when you're going to have your wings clipped by someone else at FL60 while in IMC.
Whether you'd get out or not is another matter. Maybe something like a TB10/TB20 you'd be ok, or even a 172. Doubtful in a PA28, but its got to be better than nothing.....Although I'd only ever use it in anger during a structural failure (flying into a CB might do that as well, one of my biggest fears, embedded thunderstorms).
