I think it depends on what the orthotic is trying to address. The 2160 is a structured shoe (even more rigid than the 1170), so this shoe is being worn to address moderate pronation problems. Then you are adding in an orthotic to address other problems, e.g. a high arch. If the physio knows the shoe you wear, then go with his advice.
If I was starting from scratch, I'd prefer a neutral shoe, with an orthotic to sort out all my woes.
