Low level, high speed, single engine.

Mungo5,

The thing about low inertia rotors is that they are low inertia, which is good and bad!

The low inertia rotor can be speeded up more quickly than a high inertia equivalent by a flare. The flare will transfer kinetic energy from forward air speed into rotor rpm AND the potential energy represented by height. For the same situation but low or high inertia MRs, rotor rpm will be raised more by the same flare situation for the low inertia system.

The problem with low inertia MRs is that they cannot store the same amount of energy (without overspeeding the rotor system). So the final EOL is likely to be more difficult, probably at higher speed and with more of a requirement for a flare during the EOL.
