The Q+ 15 Pro is ProKennex's oversize arm-saver, and it is built around the single idea the brand has spent thirty years refining: absorb the shock inside the frame instead of passing it up your arm. That is the Kinetic System — microspheres sealed in capsules inside the hoop, set moving by the impact, dissipating energy that would otherwise turn into elbow trouble.
Quad Focus places those kinetic chambers at the four corners of the frame, and this model carries a 25% increase in kinetic chambers, which means less shock, less vibration and less torque on off-centre hits. Around all of that sits Spiral Tech Carbon — spiral-laid graphite layers combined with high-modulus graphite.
The numbers, as ProKennex publishes them: a 105 square inch head — oversize, with the large, forgiving sweet spot that implies — on a 27.5 inch frame, half an inch longer than standard for reach and extra leverage on the serve.
It weighs 305 g with the balance at 325 mm, head light, so that extra half-inch never feels like extra work, and the swingweight is 295, which is light through the swing for a frame this size.
The beam is 26 mm, a moderately thick section that supplies stability without turning into a trampoline; the string pattern is 16 x 19, open, for spin and easy depth; stiffness sits around 71 RA and the recommended tension is 50-65 lb. Grip sizes run 1 to 4, 4 1/8 in to 4 1/2 in, and the colourway is light blue and black.
Who it is for: the player with a medium to full swing who wants a mobile, forgiving, extended-length frame, and whose arm has started sending letters. It is a comfort racquet that has not given up on being a racquet — 305 g, head light, with a 295 swingweight, is genuinely playable rather than a beginner's toy. String it soft with a multifilament and the Kinetic System does the rest.
Plužine is a town that understands being rebuilt by hand. When the Mratinje Dam went up and Piva Lake filled in 1975, the old valley and the old town went under the water, and the sixteenth-century Piva Monastery was taken apart and carried to higher ground stone by numbered stone — a job that ran from 1969 to 1982.
Somebody numbered every one of those stones and somebody else carried them. That is exactly the argument this racquet makes: the clever part is inside, and it works because of unglamorous engineering nobody puts on the poster. You will use it everywhere from a hard court by the lake to a windy afternoon above the Piva canyon.
And by the way, the kitchens up here run on lamb cooked under the sač and kajmak thick enough to stand a spoon in, so plan your afternoon match accordingly.
