There was a problem hiding this comment.
Just an idea: Instead of conditionally switching here, could we add an interface to handle the client selection? We could have two implementations, one regular, one for load balancing. Would make the code easier to read here (necessary data structures would go into the implementation) and also avoid runtime checks.
