Yeah, the extra flywheel will help, but it's not quite large enough to mimic what you get on the road -- the flywheel would need to be 2x or 3x larger.

For me, the worst is riding rollers. The inertial load on most trainers is low because the flywheels are usually small, but most rollers don't have flywheels at all so the inertial load is even smaller. I can spin way, way faster on rollers than on the road but even though the load is low my knees can hurt afterward.
