Hey Eden,
The books you mentioned are hard to find, even in our country.
You can only find it through Ebay or Amazon.
Both books are a good source of info if your planning to be a club fitter, be it amateur or Pro.
Our local club fitter keeps this like his bible.
However, there's another book which Tom Wishon wrote, his 8th actually entitled The Right Sticks
For me, this book is a better one.
Btw, Tom Wishon's wedges are superb wedges.
They kinda look like those Pride wedges...circular
