Some over here think the messenger is the best solution you can find, but I have never seen one. And I think they are no longer manufactured.
The vibrating top is important for arco. The string starts much easier with a vibrating top. The top can be from a resonance chamber (which is always too small for a earthy double bass sound) or it could be a thinner piece of wood where the bridge is located on that vibrates better than the thick solid body itself (like on some MK models that even have a kind of easily accessible soundpost).
