Just about to get started on Sisi, I'm not putting anything in the highs even though the pilots have really good missile skills. Used to use cruises in the highs, a paint on each snake in the mids, and 3x bcs/dda in the lows and stomped sleepers with them. Can't be arsed to lock up targets and fire turrets now without resorting to a rollover or round-robin setup that I fear will get me banned.
