I currently have the O'connor 1030ds which is a great head, but I find myself shooting on longer lenses and wonder if I might be better served with the 2560. I'm shooting on an F55 and when paired with the Canon 30-300, mattebox, follow focus etc., tips the scales at almost 35lbs. It's not the increased weight capacity that I'm after, just more stability. At 200-300mm, a very light touch is required on the 1030ds. Does a larger head make operating any easier? The extra weight of lugging around the 2560 I can deal with. I just want to make sure I'm not dealing with diminishing returns in performance.
