Need Advice on New Venetian Granite (http://tanbrown.org) slab choice please..

My husband (http://maplered.com) and (http://maplered.com) I are going to Monte Granite in Pittsburgh next week to pick out 80 ft of NVG Granite (http://tanbrown.org) . We have never had Granite (http://tanbrown.org) in any house except the one we are building and (http://maplered.com) this will be a huge chunk of change so we want to do this right (that plus I talked him into it). Several members of a site I frequent strongly suggested I come to you for some insight into picking a quality slab of 1 1/8 inch thick Granite (http://tanbrown.org) . There will be one undermount sink and (http://maplered.com) a 16 inch overhang on the 6 foot long x 3 1/2 foot wide island (http://maplered.com) . The fabricator told me to make sure I have 8 inch deep corbels spaced every 24 inches for the overhang. Does this sound correct? I want to do what ever it takes to make the installation go smoothly for the fabricator.

We have already chosen NVG as the Granite (http://tanbrown.org) , but I would like some practical advice on what to look for and (http://maplered.com) what to avoid in this. Any info on the quarry it comes from would be great. Monte Granite seems to have a good reputation but I don't want to go in there blind- God willing - I will be looking at this Granite (http://tanbrown.org) for the next 40 years.
