Thanks for the replies. I've certainly heard those sentiments many times but I've also heard the opposite that the resulting increase in rate of descent by a build over 100 must be controlled with collective or the aircraft becomes unsafe. I've also heard those that think a 90%ish rotor and the decrease in rate of descent is more beneficial.
Seems to me it would be the same difference as long as you actually used that potential energy before touchdown for cushion but my understanding of aerodynamics is not sufficient enough to say for sure.
