I think you'll find that this is one of the ways in which AF is useful on a macro lens. In AF-C - with a small-area AF target - you can wobble a fair amount and keep a reasonably good final image. I would have set this up to use enough flash to light the subject, so that I could be using 1/60 - 1/250 shutter speeds. (Depending on focal length, ie 60mm - 105mm - 200mm Micros.) If necessary I'd try to arrange for a Voice Operated Light Stand (TM) (*) to hold both the reflector and possibly secondary flashes, triggered wirelessly from the camera and/or hot shoe.
I tend to shoot butterflies this way. Since I normally shoot this with a D3 I don't mind turning the ISO up to 1600/3200/6400 just to get enough sensitivity, although obviously I didn't go that far with the D2x, nor would I with your D200.
I found it tough sledding with the D2x, since it has pretty large AF targets. (Ie 11 targets spread across the frame.) It's relatively straightforward with the D3 and its far smaller AF targets (51 targets concentrated on the center of the frame).
