A book is a book, and is usually biased in accordance with the writer's personal opinions and experience. I suspect that there are as many books that recommend sharply focusing on the pin.
c903,
While I am not an archery expert by any means. I did long ago realize that I am not. In this case as in many others I realized that while I am not an expert that I could still obtain advise from people that were. I respect that you are solid in your conviction however, many people on these boards profess to be experts on certain topics, however the only person that regards them as an expert is themselves. Therefore, when I start looking for opinions I go to published and documented experts in the field and start there. So when I read books published by expert coaches that have helped thousands of people go on to accomplish goals that they were previously unable to attend, then you will forgive me if I lend more credence to their opinion than I do to yours. The thousands just out weigh the one, with me. From your perspective it could be said that every book is biased if you don't agree with what it has to say and while some may be, I have a hard time being that cynical. It's just hard to argue with thousands of archers that go on to be more successful after being taught this way. JMO
