    For VFR flight at and above 3000 AGL, the hemispheric rule for the altitude to be flown is based on:

    B. Magnetic Course

    Why, because 91.159 says so. 🙂 The rational is that the magnetic course is fixed along your route, whereas your heading varies with the wind and flying is with reference to magnetic courses and not true courses.
