Brett is awesome! Just need to respect it and know what it likes, or more important, what it doesn't like. But among all the yeasts, this one has made the most mind-blowing beer I've ever had, and the absolute worst. To me it's worth the risk!
Edit - and among the various flavor descriptors, there's the lovely yak fur and wet dog. Mousy is right in there... ever cleaned up an old mouse nest in your basement, and that's what ya got! Not my favorite.
