With a wider string space, we suggest that the racket be strung at a tension of 3 lbs more than your usual tension.
The oval frame has a single vertex, which helps retain the linear motion when swinging and thus maintain the most stable inertia.
The square frame has double vertices. The greater distance between the vertices, the more mutual interference the linear motion gets. If the shot is hit at a less ideal spot, the swing inertia becomes even less stable.
LARGER SWEET SPOT
The 62-hole racket has a wider string space than conventional rackets, giving better string ductility and hence effectively increasing the sweet spot area by 40%.
Fewer holes mean improved frame rigidity and tension which allow higher stringing tensions.
LIGHTWEIGHT, LOW DRAG
More open string pattern means less drag.
Less open string pattern creates more drag.
LOW TORQUE ( FRAME )
SHAPE 03 Low Torque Frame
Improved torsional strength means minimum deformation at impact.
Conventional Aerodynamic Frame
Small torsional area results in lower rigidity and more deformation at impact.
