Tension calculator
The calculator takes this frame's verified specs plus your playing style and returns a tension in kilograms and pounds, with the reasoning behind the number.
The largest head in this batch at 105 in², built around ProKennex's Kinetic comfort system — the spec sheet points squarely at a forgiving, arm-friendly frame rather than a compact tour blade.
What the sources agree on
A 105 in² head is significantly larger than the 98–100 in² frames that dominate this list, and head size is the least-disputed lever for a bigger, more forgiving sweet spot — mishits lose less power and feel less harsh on a larger head, all else equal. At 300 g with a 32 cm balance, the weight and balance numbers alone land in familiar 100 in² tour territory, so the extra forgiveness here comes specifically from the head size rather than from an especially light or head-light build.
Where they disagree
ProKennex's Kinetic system markets specific vibration-dampening claims that go beyond what head size, weight and balance alone predict, and we don't have an independent way to confirm or measure that claim from the spec sheet — the forgiving-head-size argument is on solid ground, but the branded comfort-system claim is not something we've verified ourselves.
