I'd like to get a light weight tripod and head to support a D700, w/ 2lb -3.5lb lens, & strobe. I presume that Carbon fiber will be the lightest to carry? I presume a ball head is recc'ed over the traditional 3 plane/ 3 locking screw head, for ease and speed of mounting, positioning, following action? What height is optimum, (I'm 5'8"), and whose models are most widely used? Is there such a thing as an under $200, quality ensemble, like the Adorama ad for "their knockoff brand" that's advertised in all the photo mags? How much should I expect to spend? I would want low camera mounting/macro ability, and while on that subject, whose Macro heads (and their cost)are most widely used? ARE THERE Any special features (tripod & head) to look for that that would justify spending a bit more? Thanks.
