Short answer. If you want all the routers in your AS to have full knowledge of prefixes, buy some memory and extend your BGP cloud to include them. Otherwise, follow a dynamic default and live with suboptimal routing. Adding the third router as you suggest is a helpful option. However, in most cases, outbound traffic load is really not the problem (which is unfortunate as it's actually possible to manipulate with some accuracy) Inbound is the killer.
