I wasnt arguing either m8 maybe it sounded that way because of how i wrote it? sry if i sounded a bit harsh, The left jolt, i can definently remember the word from reading his book, if i remember correctly his 'left jolt' was basically dropping into a big step with a jab on the end, if so then there are 2 main reasons i know of not to do this as i have a problem doing this myself, first problem being if your opponent moves backwards it is easy to dissolve the power or completely move out of range of the shot, and 2 for risk of being countered, a good fighter will see you doing this and get you to reach for him then counter you knowing you will be slow to evade any on coming punches. however i may be wrong ive read a lot of boxing manuals in the past year and may have the left joltconfused with somthing else.
