Oldman I can't talk you into anything (do it, do it, do it) but I would really like for you to do this book. Your wife could help you write it if you had any problems. I think that your book would be a great teaching aid for students of all ages. I know I would buy a copy and tell everyone one I know to buy one. The best thing I could hope for is if you came out with a series of them. But, please if you don't come out with a book maybe you could start a website where we could download kata drawn by you.
