Head Light
What do they mean in tennis when they refer to head light?
if they say 2pt head light or 7 points head light. On balance
Balance: Static measure of weight distribution in a racquet and measured from the butt end in inches and/or centimeters. Commonly referenced in "points" head light or head heavy - each "point" represents 1/8 inch. Generally speaking, heavier racquets are head light to maintain maneuverability, while most of today's super-light racquets are head heavy to supply enough mass (which translates into power) to the area of the frame where the ball is being contacted. A 27 inch racquet with a balance point of 12-1/2 inches is 1 inch, or 8 points head light (even balance would be 13-1/2 inches). A 28 inch racquet with a balance point of 15 inches is 1 inch (or 8 points) head heavy. Static balance ultimately affects swingweight (see below), which is a dynamic measure of racquet maneuverability.
Basically, it's how the weight of your racket is distributed. Head light rackets are head light with less weight towards the head of the racket and more weight towards the handle of the racket. If you were to make a seesaw with your racket head and handle as the place where people normally sit, then for the racket to be parallel to the ground the fulcrum would be placed closer to the handle for a head light racket.
