So am looking at flashes to go with the D300. Notice the SB-R200 Remote Speedlight works with CLS. See a lot of links on the net and reports with people using it on the ring setup but nobody using it as a off camera remote setup for fill and lighting effects. Has anyone tried this and were your results any good? I like the idea that it is small and lightweight, perfect for toting around while traveling on vacation. I know the SB-800 is what most of the reviews talk about but if the CLS setup is built into the D300 SLR then isn't the additional circuitry, 3 more batteries, overall larger flash just dead weight and twice the cost of the lighter R200 flash?
