"This interests me because bat speed is all the rage now, and you would think that a huskier kid's meaty arms would be slower coming around, not faster. Many do not seem to have quick bat speed at all, but hit a ton! There is something going on here and it seems to go along with the observation that many big hitters seem to swing better with a heavier bat, when you would think that the reverse would be true if pure bat speed was the holy grail of hitting."

As long as you have a compact swing, meaty arms won't necessarily slow your rotation down.

In terms of ideal bat weight, it may vary from person to person. The relevant equation is F=MA. A heavier bat ups M but lowers A. A lighter bat ups A but lowers M. The result may be no significant difference.
