I recently bought an Impact stand and refelctor disk kit form B&H. It wasw ok, but the mount for the boom was a little janky. Also, they sent me the 5-1 reflector kit, but it came with a gold/silver and no black, as specdified on the web site. CS said that the black as no longer available. I'm thinking about just going with ABs kit, since I already have their lights. Does anyone have any opinions on the AB refelctor disks and mounting arm vs Impact (i.e., Ease of use, quality, etc.)
