One thing I've noticed throughout my adventures into makeup is that you're hard pressed to find a brush with the primary purpose of highlighting. Think about it, there are shadow brushes, blush brushes, foundation brushes, even contour brushes, but how many highlighting brushes can you think of? Off the top of my head, I can only think of 1 or 2. Of course some brushes have highlighting in their descriptions but it's usually just an afterthought, being shadowed by a larger use like blush or foundation. In my personal collection I use a number of different brushes for my highlighting needs, none of which were originally intended or bought primarily for highlighting, but get the job done superbly!
