I will let you know after I play a bit more with it. There may be a delay of a few days as I'm waiting on some connectors etc.
My rods have some twist/give in them. I've used some small strips for reinforcing foamies, and rods for building IFOs before... but fairly limited experience otherwise. I would assume that limited twist and flex of a piece this shape is normal though. I'm sure you'll ave a more definitive answer when a few more people weigh in
