Pretty sure you are right about that. What can happen is the .120 wall might not sonic test thick enough. It is way more consistent being drawn but it will still vary slightly. Just the chance you take with using it on a cage.
Zip, can you get .134 wall DOM?
On a side note it is pretty cool to watch them make DOM tubing. I have toured a tubing manufacturing facility before.
