Andrew,
With her ball speed and the Granite's VERY agressive cover, while it will hook more, it will hook ONLY if there's a lot of oil. PLUS, from a woman's perspective, that ball gets diry by looking at it crosseyed. She may not like it.
Also you may need to polish it and it will still hook earlier than the Nemesis.
Be careful about getting aggressive covers for low speed bowlers. I'm not saying don't do it; just be careful.
