I saw lots of FMC in the computer biz when they decided SO cord was not appropriate under the floor. The problem is I never saw a FMC connector that could actually hold FMC if there was no other support. It is clear they expect it to be secured within a foot of the connector. It was very common to pull up a tile and see a 60a Russell Stoll hanging on the THHN. You were sure happy to see a green wire in there.
