There are generally three types of tennis rackets that are measured in weight distribution within the racket. Rackets can be evenly balanced (EB), head-heavy (HH), or head-light (HL). They are just as they sound with the evenly balanced racket having the same weight distribution all over the racket, the head-heavy ones with most of the weight in the racket hoop, and the head-light models being heavier in the racket handle.
