Using a very low infill rate like 5 or 10% is great for non-structural parts because it allows you to print quickly, but the top layer often comes out poorly unless you set the number of solid layers very high; usually about 3 or 4. This ends up being rather wasteful. How about this instead… at low infill levels (say, 20% and below), Slic3r can progressively begin to increase the infill solidity a few layers before the top solid layers so they can be well supported. This will let you reduce the number of solid layers to 2 or even 1 and still get a nice top surface finish. It could do like a 30% solid layer and then a 60% solid layer, and then the final top layer would come out perfect!
