Gauge Recommendation

Overview

Solinco Confidential officially launched in 2020 after being available privately for around three years to select touring pros. The pentagonal shape provides excellent spin - comparable to Tour Bite or ALU Power Rough. What sets Confidential apart is its exceptional tension maintenance, even at lower tensions. Stiffness sits between Tour Bite (stiffer) and Hyper-G (softer). The first hour can feel stiff and board-like, but after breaking in, the string settles into a very playable feel with outstanding consistency.

Stringer Notes

Warn players about stiff first hour - string needs break-in. After settling, plays much better. Excellent tension maintenance makes restringing less frequent.

Break-in Period

1-2 hours. Critical for this string - don't judge it before break-in.

When to Replace

Every 15-20 hours. Holds tension and playability exceptionally well.
