swingweight is a measure of the racquets angular inertia - and a direct indicator of stability and manuverability.

The higher the swingweight the more effort wil be required to manuever the racquet but it will plow thru the ball effortlessly.

The lower the swingweight - less effort will be required to manuever the racquet but it will not plow thru balls as efficiently.
