I did buy a copy as was curious as to what was in it obviously. First thing I must say is that for what one gets it is not a cheap publication.
Basically is 90 odd A4 pages bound together, nice quality paper though.
I would assume that a good percentage of it has been covered in FP over the years. My usual remedy is with any article I think might be useful
from FP I just remove the article and the rest of FP goes in the bin, sacrilege I know.
The one thing about having the book is it is all in one place.
There are a few things in it that I said to myself well I never knew that so that’s a bonus.
As I am no expert on Tractions, unlike yourself, if you would like I could send it to you for an expert opinion.
