Well stated, Andy.  That was pretty much my point (although not as well
articulated) in the first place.  Anytime the clutch is depressed, there
is pressure on the thrust washers.  Although they might have better
lubrication after the car is running.  I hadn't even thought of the
gearbox issue.  I guess it proves that there is always going to be some
sacrifice no matter what you do.  Such is the nature of mechanical
things.
