With heavy shielding (a foot+ of aluminum around the crew section) to
survive a slow spiral through the belts...


But wouldn't you need that shielding anyway, in case of a solar storm?


Not really. Solar storms are infrequent and brief, so you can use a
relatively small "storm shelter" area during them.

radiation is omni-directional, or at least multi-directional.


It has some directionality, but nothing that's particularly useful unless
you're in LEO (where the directionality is quite strong because you're
just above the atmosphere).

...On the other hand, I think
solar storm radiation comes from more or less one direction: the sun.


Unfortunately incorrect. The particles in a solar proton cloud are
orbiting the internal magnetic fields of the cloud, so the radiation is
effectively omnidirectional unless you are very close to a planetary
surface.
