Add to that, manufacturer independance. I'm a little tired of Robinson vs Schweitzer, etc. Each aircraft has its pros and cons for different types of flying. I would like to see a school with ALL of the following:
Brantly B2B, Robinson R22, Schweitzer 300CBi, Enstrom 280FX, Bell 47
For PPL students, they should stick to one aircraft (for obvious reasons). For Commercial Students, this gives them a few hours in other types of helicopters... which I have found to be extremely beneficial.
