But it goes back to the old cliché "you'll catch more flies with honey than vinegar". Basically why be confrontational when you are making a request? Threats are last resorts, not the way you initiate discussion. They'd see what they could do to make those conferences whole without giving out actual $ first. That means offer to play games, maybe even home and homes with them. That is much more likely to be accepted than just sending in the lawyers and making threats.
