ayers who prefer hard-serving surfaces such as grass and indoor courts. Spalding, onthe other hand, spend four years of research and experimentation with the leading playerson the mens professional tours around the world, and came up with a long line ofracquets which were designed for specific court surfaces in 1997. Unlike Prince, Wilsonquickly responded to this challenge by making its own line of different court racquets aswell as all-court racquets the very next year. To the surprise of many, Prince ratherconcentrated on making racquets that would work on any type of court, regardless on thestyle of play. Prince, however, was the first company to introduce a same racquet model withan option of a mid-plus and oversized design. Other companies would follow up on thismethod, including Wilson. Up until 1998, over 85 percent of all tennis racquets made byWilson, Prince, and Head were available in both, the mid-plus, and oversized versions. The concept behind these options is to create a tennis racquet for virtually every type ofplayer. While generally the mid-plus racquets offer more control and less power, theoversized racquets shift back on control and add more power. Power and control alsogreatly depends on the model of a racquet and its brand. Prince and Wilson, the leadingtennis companies proved a systematic scale of measuring power. Prince for example, has its method of power measurement on a scale from 500 to1200. The higher the number, the more powerful the racquet is. Racquets under 800power level are considered to be precision racquets and are generally used by moreadvanced players and professionals. Beginners and less advanced players generally startoff with racquets with a high power level and work their way down, as their gameprogress and their skill level rises. Wilson, however, has a different power-measuringscale that ranges from 2.6 power level to 6.2 power level. Unlike the Prince scale,Wilsons power level ...
