Re your "visualisation problems", these are connected with the tricky issue of finding a polyhedral representation of the boolean solid. It does not affect the tracking of particles. You can "see" your solid as seen by the tracking by using the RayTracer or RayTracerX visualisation drivers.

Re "unnecessary surfaces", you should realise that when you make a boolean solid you incur the overhead of calculating the distances to the surfaces of all the components of the solid, so you do not really gain compared to "making up the structure of several logical volumes", as you put it. If you can make up the shape from several simple CSG solids, it will probably be more CPU-efficient than writing your own BREPS solid.
