Fantastic information, though the inclusion of Joc is bit premature.
I used "
The Making of a Hitter" by Jim Lefebvre to make my swing, and still recommend it to kids, though after reading this there have been a ton of advances since that book came out. The ability to analyze swings with modern technology has changed everything.
I was (and suppose still am) a strong left hand over top hitter (I'm a lefty/lefty) who was pure bat speed as I have very little upper body strength. My bat speed through the zone was much faster than it should have been though, which produced a surprising amount of pop. This has made me an absolutely horrendous golfer, though - too fast through the swing and too much push with my left (follow) hand.
