whats your target in the season, for winning the league solution A would be to weak in the deep, for avoiding demotion it will be pretty fine because you will have a bit extra Power in your homegame(or the game which is must easily to win) each week and could give up the other game.
When you also like to play Cup a bit, B becomes more intresting, too.
C is some kind of a personal compromise, which is think will find automatically and normally beat both extremes.
