Looks like greencarcongress has a comparison of fixed cylinder deactivation versus rolling deactivation on Fords 1 liter triple. NVH, complexity and cost balanced in the comparison. Looks like fixed is winning out in the cost and complexity without loosing too much gains in mpg. I'm not a fan of using dual mass flywheels because they fail often and at great cost in the used car market. They use them to help overcome the shakes.
