Actually, I believe they stated one disadvantage of a lighter flywheel is losing power going up hills. The engine would have a harder time lugging in the lower rpms without losing rpms, requiring a downshift when simply letting the engine lug would be the norm with a standard flywheel.

It is possible as well the flywheel you have is not as light as the lightweight flywheels mentioned in the article. A DMF is more complex and a bit heavier, while a standard flywheel is as basic as they come, but they are still heavy.
