I tend to play squad rotation in the earlier parts of the season when the games are coming thick and fast, so in an ideal world if I'm 2 or 3 goals up from a 1st leg cup tie, I tend to field a 2nd string side in the 2nd leg. Or where I have several games in 1 day, field the 2nd string against abandoned teams or teams I perceive to be weak. I have to admit though this can come back to bite me in the ass a bit more than in the earlier levels. Seems tougher to get results against even inferior opponents with my 2nd string in levels 4 and 5 than it was in levels 1 to 3.
