I have been researching these again, I had ancient ones a few years ago and didn't like them. Now, I have watched a lot of videos on them and read reviews, but id like some real world opinions on some of these. I am looking for reasonable light weight, less than 20 lbs, simple to set up in dark and of course safe as you can get. I already have a nice harness system to use for it, but none of my local stores sell these things, or only sell a couple. What do you use and why do you like it? Any tips would be appreciated.
