As for the "integrates better", I've stated my position many times but this too is BS. The only portion of the Green Line that would benefit from this is the street running section on Centre Street, which is a small fraction of the line. And not only is it my opinion that it would be a mistake to build that on street portion, it's becoming increasingly clear that it won't be built at all any time soon. Thus the only benefit really is saving a foot of concrete supports for the station platforms, which could well be lost in the need for an increased number of vehicles to make up for the reduced capacity of low floor LRVs.
