Any feedback on the Rotator Mini? I have a RD5, which is wonderful, but if the Rotator Mini works just as well at a fraction of the weight it might be a nice replacement. The design of the RD series is a vast improvement over the NN3 rotators, with the clicks coming from the side rather than the bottom. This eliminated any play. The NN3 rotators needed some play for the clicks. Does the Rotator Mini borrow from the RD series or is it an update of the NN3, as far as where the clicks are located?
