Buying my second bowling ball

Question
I have been bowling for about three years on and off.  I have a 20 year old ball "AMF ninja"16 lbs. I can generate a decent hoock with this ball for such old techknowledge. The line it makes is like a half moon.Long and smooth. I want to get a more agressive ball but, not too agressive.
My budget is about $220 for this purchase. What should I be looking for?
Any information will be great.

Thanks

Answer
Mauricio,

The stronger reaction you are looking for can be provided by your driller with a slightly stronger ball layout in a similar ball to the Ninja (is yours the original Black Ninja?). The fresh surface of a new ball will help. The Ninja was very smooth, is it still?

Not sure what stuff cost where you live, but High Performance balls run upwards of $250.00 (drilled) here. So a Performance ball should provide what you need. Do you have a favorite company? Let me know if you have any preferences and I can suggest some options.

Thanks for the question.
