Hmm ok. I can tell that my D3s operates faster than my other cameras. But with the exception of Volleyball, it's not a detriment to me.

How are your supporting your camera? Your avatar shows a neck strap. I personally know VERY few pro's who didn't abandon that YEARS ago. I shoot all my big glass on a monopod. I shoot the 70-200 offhand for volleyball, but for anything where that is my big lens, I'll put that on a monopod. Really takes the edge off over a long day.
>Back to the D600. >I have never used an add-on grip that I like.
What have you used? And didn't you like about them?

For me, absolutely.

We have very different feelings here. I actually prefer the bulk, and could really care less about the weight. These seem to be primary factors for you. I can hold a 10 pound dumbbell for a fairly long period of time. Holding a 10 pound bag of sugar is FAR harder. The difference is that the dumbbell gives me a VERY nice and comfortable hand hold. It's not always the weight that's the killer. Being able to get a good handle on the weight can make all the difference. Your bowling ball was a great example. Try to pick up an 8 pound bowling ball (or shot put) in one hand and hold it. Compare to doing the same with an 8 pound dumbbell. VERY different experience.
