I have owned a Wraptor since it was evolving out of the prototype stage in the beginning of 2010. I literally love it and have been up on it many many times, sometimes maybe 10 times in one day. I like the battery aspect of the Ronin, especially with longer life batteries these days, the lightness and seemingly more compactness of the unit for hauling and storage, but if I understand right, maybe the best thing over the Wraptor is if I can go up...then down...then back up on it again. You can stop and you can rapell from the Wraptor to do work or to come down off the machine...but you cannot go down and back up again with it. As a matter of fact, when you climb back up with the Wraptor you risk putting slack in the loop over the cog and it could pop off it and then hopefully your safety device will come into play.
Safety licensing for you will likely require this redundant protective device like the Wraptor has above the machine with an ascender attached to the machine and a strap attached to the machine's framework that you snap into your belt...so if the machine fails you just cannot fall. I never use this but most probably do.
I will almost certainly buy one even though I don't really need it with the Wraptor in my shop. But this is the future of production tree work when lifts cannot make the scene in my opinion. Good luck to you and Merry Christmas to you too.
