Perrone, The deep finger groove of the D600 pinches my thick fingers and I have trouble getting them on the small buttons (One of the main reasons I hate Canon Cameras). Assuming that you have big hands like mine, How do you like the grip? Does it spread out your hand to land you fingers on the buttons better? Does better handling make up for the added weight? I've said before that I can shoot my D800 much longer just because it is so much more comfortable.
