I finished the piping this weekend. I have four air drops, two on each side of the shop. The trickiest part was getting the long line up and over the ceiling. The Maxline tubing is relatively easy to work with, but can be a bit unruly at times. Especially when running long distances. It comes in a coil, and you can straighten it all you want, but with the thin aluminum core, it will bend when more than five or six feet is left unsupported. While trying to hang a long section, that can be a pain. Overall I am quite happy with it.
