I've been a long time user of V-Slot extrusions, but was curious what the usage case/benefits of the open rail is. Why would you use open rail when there are fewer plates/mounting solutions, and less wheels that will work on it? Does it provide a higher level of repeatability/precision? Is it just stiffer due to the added material, a spacing thing, or legacy thing? I'm all about options, but curious where you would use this except where you needed to use the metal wheels since they can...
