Hi, I have Dig's book and found it to be an excellent study on the subject. I also have all of Brown's books as well as Bakers and others.
I think Dig's book is excellent in that it's a hands on book as opposed to a historical/technical study as the other authors.
It gives good common sense and practical info in a very understandable manner.
I think Dig did a wonderful job and my hats off to him.
BB, I think you should look at Dig's book, you'll be surprised at what you'll find in it.
Thanks Dig for a great book!
Best!
Greg
