Just wanted to say that you're better off using our new, current batting charts at the Hardball Times: http://www.thehardballtimes.com/thtstats/main/index.php If you want the raw data from BIS, they would somehow have to be reimbursed for their effort. But they do have a fairly specific definition of line drives. I believe that there may be a "gray area" of 10% between LD and FB, but that's about it. Remember that a line drive isn't necessarily hit hard. It just comes off the bat on a certain trajectory.
