Barend: A new but old-fashioned dinosaur. I love my D700 but the next step is Sony A7.
Re: Too HeavyTo go with an EVF because it is lighter, just doesn't make sense. I carry a Nikon and a 6lb. lens all day long on a either a BlackRapid strap or a Spider Belt system.I suggest you look at your shoulder strap / belt (or a combination of both) before jumping ship. If weight truly is your biggest concern, get one of those little pocket cameras, they're really light!
