Ouch, my brain hurts. I've been trying to figure 4-Barrel out since I got into the book and don't know. One summer I hit the ball 50 yards farther than ever (300-325 yard carries), I don't know how, but my forearms would hit each other due to a lot of #3. Haven't been able to find that since, maybe just maybe, I had the elusive 4-barrel.
