A good quality heavy duty ball head is fine for the majority of medium format and including a typical 4x5 wooden field camera. The problem of weight isn't the weight itself but how far the centre of gravity is from the axis of the ball. So a Hasselblad is close to the axis of a ball head, so unless you are using massive lenses it imparts little leverage on the ball clamp (there is no delicate way to describe this). A large light camera such as a wooden 4x5 is also fine, the weight is still mostly around the base and near the axis. The problem comes with increasing the leverage on the ball and if you get a tall camera like an RB67, a heavier 8x10 field camera, or even a tall and heavy 6x6 such as a Mamiya C330 the higher centre of gravity overcomes the tension you can put on your ball clamp. Which is when you need a three way.

I've never tried a geared 3-way head. Can the gearing be disengaged to make large movements, or do you have to crank the knobs to make any movements at all?
Just a slight twitch to one of the tripods legs will do that.
General question: Any of you guys carry your camera around in the field with the camera attached to the tripod and the tripod slung over your shoulder? I cringe every time I see someone doing that. Looks like an accident waiting to happen.
Yes I do it. Just make sure everything's tight.
I participated in a photo session at Point Lobos with an amateur group awhile back and one guy who had what looked like a brand new Hasselblad carried it like that. Something must not have been tight because the camera came loose and fell and hit a rock. The guy was devastated.
Well, it's not brand new any longer.

I do if I'm moving less than a football field.

Ball heads have the advantage that with them one can easily correct an aiming error that does on coincide with one of the three axis provided by the three axis heads.

Steve, it could also be said that the disadvantage of a ballhead is that they can change one of the correct axes while failing to correct the one that is out.
One of the things I do is first roughly compose with the camera hand-held. Then judging the camera’s height and position, I can set up the tripod to the proper height. A ball head allows me to quickly get the intended angle. With the drag set right, there is no change to any of the settings upon locking the ball head.
I've seen many cameras fall off of those Bogen/Manfrotto quick release heads. I think 3047 is the number. They seem to be fitted properly and tighten down, but something shifts and they loosen.
