Re: If a black hole evaporates, where or how does the rotational energy go?
This is a pretty good way to look at it.

However, it's a pretty good bet that Hawking radiation still happens through a complete decay process, even if we don't know the exact rates. Also, it's a pretty good bet that frame dragging or something approximately close to it happens through the whole process. So, the evaporation process will probably carry away angular momentum through the entire decay timeline(which probably proceeds through to 0 mass with one last quanta or pair of quanta emitted,) even if we don't know precisely how fast that process will occur.
