Mainly recreational players favor the oversize racquets because they have a larger sweetspot and offer more power than midsize or midplus racquets. Widebodies Widebodies are racquets with an extremely wide frame profile, thus featuring a maximum of comfort through reduction of frame vibrations. Such racquets are also popular among recreational players, above all among seniors. Most Widebodies are also Oversize racquets. A recent development are raquets with staggered grommets to increase the sweetspot.
Every racquet has grommets made of synthetics to guard the strings.
With older racquets it's possible that the grommets are worn at some spots. Particularly the grommets of the outer mains are delicate. Once a grommet is damaged so that the string gets in touch with a sharp edge of the frame you should immediately exchange the grommets. Temporarily you can also use a string tubing to protect the string. The racquet frame is exposed to an enormous stress during the stringing process.
