Luxilon 4G has been my favorite so far. I can string that up tightly and still find plenty of comfort and all the pop I want while control and spin is great. I also like Solinco Tour Bite 16 as the firm/low powered feel is ideal for the power I find hitting with the C10 Pro.
With livelier polys, I string them up tighter. I went from 52lbs with the Prestige MP to a 55-57lbs average with the C10 Pro.
