I took your advice, but I didn't apply it to my fictional association-- instead, I applied it to my Replay_1997 association where I'm managing the Marlins (hopefully, to the World Series). Five games into the replay, I assigned all of the parks for all of the teams as you suggested. This is what my lineup looks like now, and it looks "realistic" if you ask me. We're 60-games in and in first place by 2 games. The only slight deviation is that Sheffield has 20 home runs already and Devon White has 9 (compared to their all-of-'97 totals of 21 and 6, respectively). This is what we look like:

It's amazing what a difference the real parks make!
