> > Great Post and answers...just found this site and it is very intriguing......but in regards
to the information in regards to bat mass vs speed......am i correct in saying that a 30 oz
bat swung at 68 mph will cause the ball to travel further than a 28oz bat swung at 68
mph? Of course all other things being equal?

vs the bat speed lost by doing so? For example...if you could swing a 33 0z bat at 65 mph
or a 30 oz bat at 68 mph, which would be the more desirable option....all else being

more important to generate bat speed than it is to get bat mass. A ball will travel farther
when a heavier bat is used if a hitter was able to use a heavy bat plus swing with the
same velocity of a light bat while hitting in the center of percussion. The problem for
most mortals is that they cannot swing a heavier bat as fast. I don't know anyone that
can swing a 42 ounce bat as fast as a 33 ounce bat, including Barry Bonds.
