Yeah, I mean it is really user preference. Having played several game, I feel that pro style rushing attacks may get a small boost with these at 35 but nothing that is too terrible. You may have a game, where you feel like the CPU is "super" but it averages out in the end. I had Air Forces running back for for three bills against me in one game, and in the next I shut the cpu down. But I don't think you will see a major shift if you altered the slider with each team. Give it a try and let us know how it goes!
