Is hitting with a super light bat counterproductive?

Years ago it was thought that with a heaver bat you could generate more power to hit home runs. Today Ballplayers use lighter bats to generate bat speed which is proven to be more productive to hit the ball harder.

A "super Light" baseball bat could be counter productive because it might alter the hitters natural swing. Timing could be effected depending on the hitter strength causing the bat head to be too out in front. If the bat is too light it might also be harder to control the bat through the hitting zone when coming in contact with the ball. -Steven KeyMan
