My purchase of this addon was purely by impulse, the moment I saw that ORBX was advertising its release on Facebook (even before the announcement here). Until seeing the posts by Daube in this thread, I had never been aware of the Mamudesign power lines addon (either freeware or payware), so I was under the impression that this ORBX offering was the first and only of its kind. My first impression was that the ORBX addon looked really good in the screenshots on their page and on their website, but I should have spent more time looking at them closer. I was quite disappointed when I discovered after purchasing and installing the addon that the wires don't actually connect from one tower/pole to the next, but the real nail in the coffin for me/what led me to uninstall the addon, was that there is a visual hierarchy issue (and likely lack of LODs as well) in that even when you're flying at very high altitude, such as 10,000 ft, over the tops of thick clouds, when you look down you can see all of the power line towers from the ORBX addon visible through the clouds.
