Quality string, a little softer than some Poly’s. You will save some money and not loose any preformance from this quality string. Once I tried them, I was sold!

A great all around softer poly with exceptionable durability.

Great string for a great price. Nice power with durability.

Very controlled and vibrant, and with enough feel so that you know how hard you're hitting the ball without losing comfortability. Also produces good spin comparable to RPM.

Great co-poly with softer feel than most. Good tension maintenance when strung in mid 40's with ample, controllable power due to its spin-generating qualities. Overall a great value!

i used to play with rpm blast but the feel wasent that well and the string maintenance wasent good ether. in like 3 weeks it needed new strings. when i tried black magic it gave better power control but still lower spin. but still i like playing with these more. it is also very arm friendly.

Plays like a multi being very soft and arm-friendly but has all the benefits of polys, control, spin and of course durability. Very unique feeling string.
