Yes Tao is a great engine. I have seen some great attacks from it on FICS.

I must say however, and I didn't mention it in my original post that I don't use
the default book. The book I use was made over the last few years. It was
originally based on the gm2600.pgn, but then I switched to a large database I
compiled myself.

It is a very good book, and I edit it almost on a daily basis.
