I would have liked to have them included lefty/righty breakdowns for the pitchers too. From what I understand the lefty/righty is only taken into account on the batter's card not pitcher's. The only thing I think it's lacking is a comprehensive lefty/righty system. I do like the way replay has you add up both numbers then look at the result. I don't think in real baseball it's a 50-50 proposition it always kind of bugged me when a pitcher who gave up like 2 home runs all year would give up a lot of homers on the hitter's card. It's been a while but I think In strat 1-3 you look at the pitcher's card and 4-6 the hitters.
One thing I liked about replay over strat and dynasty is that the roll is combined not split. Like you I like to know what is going on.
