Players seeking a more arm-friendly control string will
enjoy the playability and overall feel of Pulse. For
this string, Isospeed uses its signature Double
Heating technology - a manufacturing process that
evens out the irregularities and eliminates internal stresses.
The result is more uniform elasticity. Ultimately, this is a
great choice for big hitters looking for control, spin and
durability without the harsh feedback found in many

Offers slightly more
durability and directional control than the 1.25 and 1.20
