The thing is, you have to consider the whole fluid absorbtion, not just piston areas. In my experience sliding calipers require a lot more travel so even though the areas are less the volume required is more. 4 pots etc have a much stiffer structure and more defined seal roll back (designed to stop drag) with less travel. Once all bedded in travel required will reduce which will help. Always best to keep to the smallest you need as it will give a longer, more easily controlled, travel.
