Do LF/RF park effects really matter in this game? Should you load up on RH pull hitters if you play in a RH-friendly park like DET? Should you load up on RH starters for the same reason?

One reason I ask is because it seems to me that almost all homeruns go opposite-field!

Is the game really simulating the direction of ball flight, or is it really kust ther overall park effects that come into play?
