Higher voltage and efficiency

If you don't need to go up in voltage why consider it? Is that revo for racing? Sounds like you have a smooth finger so the gains will be less than if I were to race that setup and move to hv.

Hv setups usually have more grunt right? Is it possible some people learned to be lighter on the trigger as a result?

Hum... No, HV and low Kv have less grunt, because the motor has higher inductance, so it limits amp spikes too.
A LV setup need a smooth finger to spare some mAh and limit amp spikes.
