Still in Black X10 20m Reel

STILL IN BLACK X10

Still in Black X10 is a round co-polyester built around the brand's Dual Dynamics technology — a balanced, versatile string that pairs performance with a comfortable response. It comes in blue.

It is one of the two all-rounders in the range, with X12 offering a firmer, more powerful version.

On-Court Performance

The stringbed is firm and low-powered, giving a predictable, controlled response.

Tension maintenance is reasonable for the price, so it stays consistent over its life.

Comfort is limited — string it toward the low end, especially in a full bed.

Who Should Use It

• Advanced players who want a firm, cheap control poly

• Flat and all-court hitters who supply their own pace

• String-breakers who want a durable round poly

• Hybrid users wanting a firm poly component

• Frequent restringers

Who Should Not Use It

• Players with arm sensitivity

• Players who want spin bite from the string

• Players who need help generating depth

• Beginners

Hybrid Setups & Performance Adjustments

Power
String low, or pair with a multifilament in the mains, since it adds nothing to depth.

Control
A full bed at mid-to-high tension keeps the flight low.

Spin
Pair with a shaped poly in the mains for bite.

Comfort
Firm — drop tension or hybrid with a soft cross.

Tension Stability
Reasonable for the price — restring every 12–18 hours.

Durability
A thicker gauge extends it.
