I had the same experience. The grip added a lot more weight and bulk to my D700 than I had expected. It's not as big and weighty as the 1964 Buick Electra I once owned, but it's getting there! As a result I have not used my grip very much. I may try it again if I'm using one of my light-weight 50 mm. or 85 mm. primes attached to the D700, but not if I have a beast like my 80-200 f/2.8 attached. I like to travel light and am glad to have the D700 where I can opt to leave off the grip if it's going to be a drag to lug the D700/grip combo around all day.
