this is said to be the book that holds the most sound advice about hopping. i myself don't hop and my knowledge on the subject is limited. but if you want to do it i believe that studying and becoming as informed as much as possible on the before hand, is adamant. some say Littlejon sugar coats some aspects but the rest is pretty on point.
