i asked the same question 2 years ago wth no response . i am looking for the 16 pounder black ninja also. I had mine before i half knew what i was doing now i think it would be a great ball for med to light conditions.i will take it oin any condition. I bought a fury and it is like starting a fire with wet leaves ,an occassional spark some, smoke ,and then the fizzle when u think you have something.
