I'm one of the lucky ones too.  When I did my timing belt using this
method, I found the crank bolt to not be as tight as past discussions
would have led me to believe.  It didn't seem to be overly stressful on
the bellhousing or flywheel IME.  All cars are different tho'.

I think a worse method is to put the car in gear and have someone stand on
the brakes while you undo the crank bolt.  How's that for a sick method?!

I would be interested in hearing of some BTDT of bellhousing/flywheel
damage from using the tranny bolt method.
