I never have used a brush to apply el to the waterline, but I have MAC fluidline and use a smudge brush by beauty secrets, a line from Sally beauty supply. It works better than the smashbox and bobbi brown EL brushes I have and cost probably less than 1/3 of what they did. Try Michael's (craft store) too- I have alot of paintbrushes that give stellar performances on MU application.
