Lightened Flywheel -2.0l 16v

[rocco16 at sbcglobal.net (Larry Fry)]

Ron brought up some valid, logical concerns.  But concerns are all they seen
to be.
I must ask this: has anyone actually noticed any of these issues with a
lightened flywheel?
I know I didn't.
As Ron pointed out, many of those were "potential" issues only, not
necessarily actual.
