Super 77 is going to run you a bunch of $$. If it is white, you probably won't have much of an issue. I don't think there is a whole lot gained by the insulation of the panels. The radiant barrier helps a lot, but the ambient temperature soaks in anyway. They (foam panel) are more efficient, I'm sure. But in the heat of the day efficient and comfortable can still be a ways apart.
With the panels being thinner, a smaller structure will work in your favor. By smaller, I'm referring to panel sizes not being 4x8. Not necessarily a small yurt design. Another thing you can check out, if you are bent on radiant barrier are the glass bead paint additives. There is a company that markets paint and paint additives. I believe that there are also aluminum based paints for the same purpose. If the board is white, you won't have to worry about 165F. Now, if it's black, everything changes. You will want that mylar.
