Benedetto's archtop build book

Kalimna

Greetings folks,
For many years Ive owned Robert Benedetto's 'guide' on how to build an archtop guitar - a fabulous book that teases the steps in order to construct an instrument, for instance several pages on wood selection and about half a page on graduating the arch.
Anyway, I see there is a new edition out (3 years ago) of this book, and I wondered if anyway has experience of both and could offer up if there is anything new/worthwhile in the new edition?

This is before I start my long-gestating archtop build (in the manner of a Gibson L5). I actually started thicknessing sides yesterday but woodworm had attacked and the sides are now fire-pit fodder.

Cheers,
Adam
