I don't pre-load either,but to hit an HR that's a proven method. I was just trying out MVP12 on the stock settings which was all sliders at "0" and pro-mode. So far after 19 games Matt Kemp has 16 HRs so I agree with you daflyboys, kinda unexciting. I'll have to adjust for difficulty.
So, speaking of difficulty, does anyone have any interesting slider combos or recommended datafiles? (This may be for another thread) The hitting seems way easy so far, but the pitching seems great. On the same game in which I hit 13 Hrs, Clayton Kershaw was hit for 5 runs all off mistimed pitches.
