Book Thoughts?

[phillipa]

What does anyone think about this book. The Bit and the Reins: Developing Good Contact and Sensitive Hands by Friderike Butler and Gerhard Kapitzke.
I bought it a year or so ago and am now re-reading it. I like what they say about the use of the bit, softness, lightness, acceptance of the bit and the explanation of different types. My only worry is about the constant reference to the `driving seat'.
Anyone have any thoughts....
