Isometric: Developed over 30 years ago, the Isometric design increases the sweet spot by 7%. Compared to a conventional round frame, a square-shaped Isometric racquet generates a larger sweet spot by optimizing the intersection of the main and cross strings. Isometric delivers greater control without sacrificing power.
Liner Tech: Straight hole grommets elongate the strings to optimize power and comfort on off-center shots.
Oval Pressed Shaft (O.P.S): Shaft corners are rounded for an ideal flex at impact to increase dwell time for optimal spin and directional control.
Aero Shape: By varying the outer angle of the aero-shaped frame, the middle and upper hoop are plush, while the lower hoop is stable
