Kirschbaum Pro Line 2 Rough 12m Set

KIRSCHBAUM PRO LINE 2

Kirschbaum Pro Line 2 is the brand's long-running flagship and the string most Kirschbaum loyalists started on. It is a soft, supple round co-polyester built for power and comfort rather than raw control — an easy, forgiving poly at a low price. It comes in black, with a roughened Rough version for extra spin.

It is the comfort-and-power end of Kirschbaum's range — softer and more powerful than Max Power or SuperSmash, and a sensible first co-polyester for a player leaving multifilament.

On-Court Performance

The stringbed is soft for a poly, with more free depth and a more forgiving pocket than a typical control string.

Comfort is a real strength — a full bed is tolerable for many arms that cannot use a firmer co-poly.

Control is moderate; the trajectory sits a little higher than a stiff control poly, so it rewards players who add their own shape.

Durability and tension hold are good for how soft it is, which is a large part of its long-standing popularity.

Who Should Use It

• Players wanting a soft, comfortable, affordable co-polyester

• Intermediates trying their first poly

• Club players with mild arm sensitivity

• Hybrid users who want a forgiving poly cross

• Longtime Kirschbaum players who like the classic feel

Who Should Not Use It

• Advanced players who want a firm, low, precise control bed

• Heavy topspin baseliners who need sharp bite (choose Black Shark)

• Players with serious arm injuries who need a true soft string

• Players who want maximum durability above all (choose Max Power)

Hybrid Setups & Performance Adjustments

Power
String toward the upper window, or cross with a firm poly, if the ball runs long.

Control
A full bed at mid-to-high tension tightens the response; the Rough version helps too.

Spin
Choose the Rough version, or pair with a shaped poly, for more bite.

Comfort
Already one of the softer polys — drop 1–2 kg for maximum arm relief.

Tension Stability
Good for a soft poly; restring every 15–20 hours as with any co-poly.

Durability
Use a thicker gauge, or step up to Max Power, if you break it quickly.
