I don't have an issue with skinny 10s too much as long as it's the same for both teams. Coaches (in all sports, I guess) are the biggest hypocrites going, though. They ask their own players to push their luck; skinny 10s, holding down in the tackle, etc, and moan when the opposition do it. We complain if refs are continually blowing up for pens, disturbing the flow of the game. And we complain if they don't act when we perceive the opposition offside. It would be a simpler world if everyone stuck to the rules, but human nature being what it is...
