I won't argue about the FITA coaching book with you, I haven't read it, I can't afford to buy it at the moment, if it was available as a download (like "the backward"
GNAS have made the rules etc available) I'd read it. The best coaching manual for beginners that I have read is the NAA manual and I would like to see
GNAS adopt a modified version of this. (Unless the FITA one is better, which I'll judge when I do get around to reading it)
I will argue with your opinion of coaches in the UK. Most coaches in this area do have open minds and are willing to learn. I know that there are exceptions to this, and I wish I could do something about them, but remember most coaches are only there because they want to help, and most of them (at least in my experiance) do a very good job. Please don't tar all coaches with the same brush, as I have said before if you can't find a good coach, you aren't looking hard enough, they are out there.
The other thing to consider is that not every archer has an open mind, nor does every archer wish to improve. This is one of the things that it is hardest to accept as a coach. I have had archers insisting that they use poor technique, or equipment entirely unsuitable because they like it. Even when it is proven to be detremental to their scores. I have also seen archers tell coaches to leave them alone because all they want to do is throw a few arrows at a target, and don't care about the results. As a coach I find this very frustrating, but know that I am wasting my time trying to help these people and leave them to it.
