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.
