Benro and Manfrotto Monopods - QR System
Have you considered buying an entirely separate set of QR plates to unify your entire setup? For instance, in our setup, we use a tripod, a monopod, and a GlideCam with various attachments for each of these (rail systems, teleprompters, etc.). By adding this (relatively) cheap QR plate to the top of each stabilization method, we can switch our cameras around all systems with ease, and the QR plate can go on any standard 3/8" or 1/4" screw.
