I'd like to know the nitty gritty differences between the two versions, other than just what the brochure says. I'd hate to buy one, wishing I had bought the other. Im going to be using it both for flight and handheld. I watched the tutorials and noticed the very nice flip-clasp system used for releasing and tightening adjustment points on the M10, but on the photos of the MR version it looks like hex bolts are used instead. This is the kind of thing that makes a difference in ease of use to me. So I'm not sure if those are older prototype photos of the MR, or are they really just using the hex bolts to save weight for the MR version? Same with the roll tube, being an actual tube on the brochure photos vs a frame type construction on Tabbs instructional videos.
