Practical western training

It has been a while since I read this book, but remember that I found it very informative on a broad variety of western training questions, and can recommend it for anyone who wants to add to their western training library. The main reason I'm writing this review is to see if there is someone out there who might be able to recommend a book to me... I have been searching for a good book that focuses mainly on training and using the Bosal Hackamore. So far, I've had no luck. Perhaps someone out there knows of such a book and could post it here for me! I'd be tickled to come back here and see such a recommendation! Thanks for your kind attention!
