I can't tell about any best practices as I don't have the mount. I love the tiny size and light weight of that mount and big carrying capacity but am unsure about the backdriving issue. I would like to image unattended, at least some of the time and I'm sure I couldn't sleep, worrying about it, so I'm holding off.. I'm looking at a couple of other mounts too but I keep coming back to the rainbow. I didn't read the whole thread on CN, was there any talk about a brake for the 135 like they have on the 300 model?
