L-TEC strings are specifically designed to offer optimum playability at lower tensions. A maximum tension of 52 pounds is recommended. As a general guide; when using a midplus frame with a 16 x 19 pattern a reference tension of 44 pounds produces a stringbed stiffness and playability that works nicely for advanced players as well as the general tennis playing public. The same size frame with an 18 x 20 pattern does well with 40 pounds as a starting point. These suggested tensions are not set in stone, they are meant to be a guide.
Most copoly strings perform best in this lower tension range. While it may seem excessively low for players who have been raised on synthetic gut and natural gut strings, it is important to note the elasticity of copoly strings is far less than a synthetic or natural gut. With traditional synthetics the axiom of stringing high for control has merits because it helps reign in the inherent power that elasticity produces at lower tensions. L-TEC Premium copoly strings represent a new paradigm in string construction and have at most 1% - 2% elasticity. Our strings need to be strung at lower tensions in order for players to realize and fully appreciate the optimal performance characteristics.
Lower tensions applied to L-TEC Premium strings allow the player to produce powerful shots that are under complete control with much less effort than copolys strung at higher tensions. The lower tensions promote greater string movement/snapping action that enhances both the amount of spin and control. The lower tensions, when applied using the JET Method of stringing, allow the stringbed to provide at least 2x - 3x the efficient playability compared to other copolys at higher tensions. The lower tensions allow the player to experience comfortable hitting sensations even though the strings are designed to be stiffer and have less elasticity than synthetics and natural gut. Lower tensions, when strung using the JET Method of stringing, provide a stable stringbed that remains constant and stable losing very little tension throughout the life of the string.
