What is the hurry? WhenI use my large format camera I am never in a hurry. This beautiful format has ben designed to allow you to slow down and enjoy the surroundings as well as your work. Part of the job is setting up your camera properly and looking so that you have a chance to previsualize your final image. If you are having problems get a field camera. This will make your load lighter and easier to carry but won't set up any faster than your rail if it is setup correctly.
My suggestion is slow down and enjoy your craft.
