The Bogen/Manfrotto users have it(at least for me)I bring my Bogen/Manfrotto tripod with 3030 pan-tilt head and never have any problems.I always bring two plates(as I always bring two cameras)screw them in before I even go out the door.Then I can switch(especially if using two different films)with ease.Go to your nearest store and play around with the displays-see what's right for you and have fun.
