What is the best way to cut sink holes in a Granite (http://tanbrown.org) slab?



I am installing Granite (http://tanbrown.org) Counter (http://GialloFiorito.com) s in my two bathrooms and (http://maplered.com) was wondering the best way to cut out the sink holes. I am using overmount sinks so they don't have to be pretty but I don't want to ruin the slab either. I was thinking either a grinding cup or an concave blade. I don't mind spending a bit more on a blade that will save me some time so I was wondering what the easiest way to approach this would be from someone that has some experience in this. Thanks so much.
