Bolded for emphasis. Though I would probably try 4000 without polish first, throw a few shots and then add polish if it's still not hooking enough.
Either way, if you don't like the reaction of a ball, first thing to do would be to alter the surface!
Also, is there a balance hole? Are there three holes in the ball or 4? If you add a balance hole in the P3-P4 area, you can enhance the hook, potentially by quite a bit.
