I use a Hammer Vibe reactive Resin ball for my power ball and an Ebonite Maxim for spares?

Ebonite Maxim for my spares and dry conditions. I need something in between the two. I was thinking of buying either the urethane Brunswick Avalanche blue one or first in it's series of least hooking Avalanche balls or the Ebonite Nitro. It says that the Nitro is sanded but by how much. I'm afraid that it will not do what I want it to do, and that is hook a little bit more then the plastic one. I need a ball where I can play slow conditions around 15 to 12 board but go out to about the 10-8 board, so not to go out to the reverse block condition I run across once in awhile. A more gradual curve into the pocket would be nice too. Does anyone have any knowledge of what I'm talking about. Thanks for you help.
