for me:

*208* for fluidlines and lining (i had the 266 but it just doesent work as well for me. the 208 is smaller and gives me better control, it makes lining with fluidlines SO easy!)
*116* for blush and skinfinishes
*242* for paints, eyeshadow and concealer (i looove this brush!)
*213* for eyeshadow, brow bone and light wash wash
