Correct me if I'm wrong,
but when I did an FI rating, I had the IMC added on account that I had an IR. In those days, there was no UA in the IR.
So, I was not trained to recover from spins/UA under the hood, particularily when you consider it'll almost certainly be partial pannel.
Unless things havce changed, I'd suggest VMC. Infact, when I redid my IR last Jan, we always did it VMC. No exceptions.
