I have been working with the Arca Swiss B1 for more years than I like to admit and have found it reliable and worthy in all situations including extreme cold weather - Never had it lock up as I have heard in reports.
As of this weekend I am going to retire my Arca Swiss B1 and am switching to the RRS B55 for the following reasons. *
I gave myself the blindfold test. * Both Ballheads were setup on a Gitzo 1348 tripods with 1Ds Mk2 cameras with B57 L plates... mounted in RRS quick release clamps. *
I found myself instinctively perferring the large tapered knurled tighting knob of the RRS B55 *I also preferred the tension nob located on the right as it was easier to access and control than the embedded tension nob on the Arca Swiss B1. *
After spending the rest of afternoon shooting without the blindfold I was surprised to find that I had adapted to an unfamiliar tool so quickly.
I was most surprised to find that in switching from ballhead to ballhead , my experience with the Arca Swiss increasingly became less pleasant. *Think about the following....when you are looking throught the prism of the camera your hands are making positioning decisions that are based on touch and memory. *I am not saying the Arca Swiss B1 is a dog as it has served me well for many years.
I believe that the RRS B55 is ergonomically better suited for human - touch memory - wiring; which allows one to forget the Ballhead and concentrate on the capture of images.
I will not get into a cost debate, because I remember arguing while in my youth, why the Corvet was a better car than the Porsche; when I secretly knew that I loved the Porsche but could not afford it .
Besides the cost differences are quite small when you think a great ballhead should last forever
