You got that right Josh. There is no set...none...that works for Coach mode. I have tried them all, including my own set(s). None of them hold up for more than a game or two. The system is broken. EA does not want you playing coach mode. The game engine and all surrounding it is tweaked for user vs user. Anything involving the CPU AI and decision making is fubared.
It's why it is 9 months later and people are still creating/tweaking slider sets. It is a hopeless exercise...especially for coach mode.
