Which ones would they be? Assume there is no knock on effect, just a simple retrospective change with everything else being the same. You can either choose 2 sets in the same match or spread across two matches.
For me, its either
2 sets in FO 06 (7 straight slams, grand slam, double career slam) or;
1 set each W 08 & AO 09 (7 straight W's, 8 W's total, 5 AO, H2H factor - reversal of 2 worst losses to Nadal)
