Yael, I think you've taken that the wrong way. I was making some general points but you seem to infer I was directing them at you. I apologise now if I've offended you.
1.The book is a companion to the original
2.On it's own, it doesn't provide you with a training programme
3.It's S&C not skills
4.I think the title is silly
5.It's about methods used around the world, many of them very similar
6.If you can afford it, it's enjoyable, if you're in two minds about spending the money then spend it on something else, maybe the first book (which, I might add could be improved a lot)
