Solinco Confidential & Confidential Soft Tennis String Review

Solinco built its name on Tour Bite and Hyper-G, two polyesters that sit at opposite ends of the firmness spectrum. Confidential was built to land in between, keeping the pentagonal shape that makes Hyper-G a spin favorite while chasing a feel that neither of Solinco's other polys quite hit.

Feel and Comfort

Tension range matters here Solinco's recommended range for Confidential is 45 to 50 pounds, and this is not a minor suggestion. String it stiffer than that, and you will get a firmer, more closed-off feel that fights the string's design instead of working with it. Stay inside the range and give a freshly cut string bed a day to settle before judging it, since the feel keeps evolving even after the strings are cut in.

The first few swings with Confidential feel firm, almost dead, closer to Tour Bite than expected. That first impression does not last. After roughly an hour of play, the string bed loosens into something noticeably more comfortable while holding onto the control Solinco built its reputation on.

Power and Spin

Strung on the lower end of the tension range, Confidential holds its tension longer than most polyesters manage, which matters most for players who already prefer stringing light and normally fight fast tension loss as a tradeoff. On output, it lands between Solinco's two other polys: more power than Tour Bite, less than Hyper-G, with the pentagonal profile still producing real topspin on groundstrokes and enough pop to finish points when the swing opens up.

Durability

Confidential's shape slides against itself cleanly, so notching stays minimal even with a fairly sharp profile. Testing in an 18 gauge, 18x20 setup, the string held its performance well past what most polys manage before going dead, with a longer usable window after break-in than the average co-poly delivers.

"It felt really good. The strings felt much softer, pretty comfortable, and not as stiff as Alu Power. I got more depth on my shots with less effort, so I'd call it a bit more powerful than Alu Power overall, somewhere between LXN Smart and Alu Power. I strung it at 55 pounds in my Wilson Blade 98 CV 18x20." Max Ziegler, Tennis Express Playtester

"I found it crisp right out of the gate, without much free power or spin. It did not take long for the string bed to settle in and adapt to my game, and the spin and power picked up from there, though I felt it lose some of that initial crisp feel over time. I loved the pop off the string bed. I strung it at 48 pounds in my Wilson Ultra 100 CV Reverse." Chris Virk-Brown, Tennis Express Playtester

Meet the Softer Sibling: Confidential Soft

Solinco later expanded the line with Confidential Soft, dressed in a bright pink colorway and built for players who wanted the same directional control and spin as the original but with more forgiveness on the arm. The shaped co-polyester construction carries over, just tuned for extra plushness and a softer response off the string bed.

The Verdict

Confidential earns its spot between Tour Bite and Hyper-G. It gives up none of the control Solinco is known for, holds tension longer than most co-polys at lower stringing weights, and settles into a feel comfortable enough for players who found Tour Bite too harsh. If comfort matters even more than that, Confidential Soft gets you the same core identity with a plusher ride.
