The Wilson Extreme Octane 17G (now widely known and marketed as Wilson Synthetic Gut Power) is a high-energy synthetic gut string designed for players who want a "crisp" feel and a boost in power without breaking their budget.
The Extreme Octane features a solid monofilament nylon core surrounded by high-energy "X-band" outer wraps. This construction is a significant step up from basic nylon strings; the solid core provides a stable, responsive feel, while the outer wraps are engineered to increase energy return. The 17-gauge (1.25 mm) version is thinner than the 16G, which allows for deeper ball "bite" and a more lively string bed.
Performance Profile
- Power (8/10): The high-energy wraps act like a springboard, providing excellent depth on groundstrokes and extra "pop" on serves.
- Feel & Control (8/10): Because it is a 17-gauge string, it offers superior feedback compared to thicker gauges. The "Octane" core ensures the string bed feels crisp rather than mushy.
- Comfort (7/10): It is very arm-friendly for a solid-core string, making it a safe choice for players who find polyester strings too harsh.
- Durability (5/10): As a 17G string, it prioritizes playability over longevity. It is more durable than many multifilaments but will wear out faster than the 16G version or a polyester.
Best Suited For
- Club & Recreational Players: Those looking for a reliable, all-around string that performs well in every area of the court.
- Players Seeking Feel: The 17G diameter is ideal for "touch" players who want to feel the ball on the strings for better placement on volleys and slices.
- Budget-Conscious Competitors: It provides a high-performance experience at a fraction of the cost of premium multifilaments like NXT.
- Hybrid Setups: This is an excellent, crisp "cross" string when paired with a polyester "main" string to add comfort and power to a control-oriented racquet.
Pro Tip:
Wilson recently rebranded this string as Synthetic Gut Power. If you are looking for this exact performance in the future, the packaging may say "Synthetic Gut Power," but the construction and playability remain identical to the Extreme Octane.
