Have to admit from my stand view that I don't think Barnes was especially fair, he seemed to ignore some blatant offsides and then not, which is sort of his trademark, and we got the worse end of those decisions as we spent most of the second defending. He certainly copped for a bit of stick, not that it means much.
At scrum time I much prefer the SH approach, one bite at winning the pen, ball available use it. That does not alter the fact that our scrum creaked,of course, but Quins were over rewarded for it.
