I should have done my research before asking the question here, but Gary Taylor in TVS video 4 did tackle the issue in video 4, about nine minutes into the show:

He demonstrates the difference in sound between the two techniques.
The video is worth watching again in its entirety actually. Thanks, Paul, Gary, Spike, for sharing so unselfishly.
