Wow I'm surprised at the 217 comment--I faithfully use this to apply crease and blend, its awesome for that, but I can't imagine getting the coverage I'd want from a paintpot using the 217.
I use a small shader brush (cheap drugstore brand--IMO the brush to apply a paintpot does not need to be expensive or fancy at all, I can always get these cheap shader brushes to apply them thinly, and nicely so that sometimes I don't even put shadow overtop). Of course, I'm otherwise a faithful MAC/Bobbi Brown brush girl--they make SO much difference IMO for blending and applying foundation, shadow, etc.
