Try the Monks brushes- they aren't goats hair but I have those and prefer the Monks for some things, unidirectional applicator for other things. Some of it comes down to how it applies and what you are trying to accomplish with the applicator. I've tried quite a few and everyone seems to have a preference.
You might want to read some of Neil Antin's work on filtering. There's a whole lot to that area that was unknown to me starting with the specs and what an "absolute" rating means in terms of granularity. (I'm not a materials science so I'm sure there's a better way to describe that).
