Joe,
Very interesting comments. Thanks. I will have to look at the swing speed radar but I don't see myself making a purchase like that this late in my "career".

About the measurement you mention: Do you know what measurement numbers would be considered optimal or most desirable when calculating them? Also, I think it was on this site that Jack or someone else mentioned the best effect was achieved by gripping a bat at the base of the handle. This calculation you mention would seem to suggest choking up on a longer, heavier bat would possibly produce a more favorable result. Comments?

Average the scores (speeds) for each bat. Then, basically pick the bat at the point at which your average speed for the bats just begins to drop.

As I recall from college, I think they called that the moment of inertia. In other words, you can actually swing a "heavier bat" faster than a "lighter bat" if the center of mass of the heavier bat is close enough to your hands.
