I bought the Book Slingshot Shooting by Jack Koehler, I picked up a couple tid bits, then loaned it to a friend and he got a little out of it. Honestly, there is better information in SS forums and the SS comunity. If you think you might be interested in the book all I would want is shipping cost, PM me and let me know your location and I'll find out the cost. I paid full retail but don't feel right selling it because my opinion of it is just so/so. Heck read it and pass it on. Might be best for someone just starting. Thanks.
