I like to just find the right spot and freeze it at zero. I play on Veteran + for hitting and All Star + for pitching, with a lot of other sliders working as well. I feel that I get a game that gives a lot of variety in challenge based on how good the opponent is, the weather conditions and the umps, and that I'm generally rewarded for doing the right thing and punished for doing the wrong one. Its the best sports game I've ever played at being able to do that, and I've been playing them since the 80s.
