I scanned an few of them at B and N and the good ones seemed to come from DU. If you really want to read some good stuff, read all you can off this forum. Many more secrets given away here than ANY book you will ever come across. Also try a membership with DU or another group during the off season. The books will help you to learn the talk and basic stuff, but every day is a different situation and calls for different tactics. EXPERIENCE is your best teacher and I bet there is over a 1000 years of it here.
