In heavy carry down, you generally need to relatively, in a way, ignore the backends. You, again, generally need the ball react more in midlane and less in the backends to get rid of the inconsistency, over/under of the heavy carrydown.
Therefore, drillings providing early roll, midlane read, with relatively less flare potential are found to be ideal to combat with the heavy carrydown by many bowlers.
Of course, you need to adjust the cover according to the amount of oil, transition, and the condition of the heads in order not to let the ball "hook-out" or loose its energy too early.
