I have been using the under running water method since I started. A very small stream seems to work faster. I just run the water at the base and slowly rotate as I see the tips get waterlogged. When the tipside is smooth with water instead of pointy with just tips, I just let it hang tips down for a moment letting excess drain, maybe a quick shake to get some more water off, then start my swirl in the cup. It is kind of tricky to find that sweet spot for water, but the brush can hold too much water for the soap. It takes a long time to make enough lather to keep it from being to wet of lather. Its more efficient to get too much water out of the brush and add more if needed. You probably already know all this, but maybe you can gleam a tidbit from it.

I am really thinking I will like a scuttle, by the third pass the lather is pretty cool. With the hot weather on its way in, the cool lather may feel nice with the heat compounded by a steamy bathroom.
