Where would you say that the trade-off is between dynamic and static if both are represented by best of breed representatives? Something like Erlang or your favorite Lisp? Lisp is a great language, but I still think static typing wins at a certain point for large projects. Type signatures (which are automatically inferred) provide a certain amount of documentation, and static typing also makes for cleaner and inherently more comprehensible interfaces. When you have multiple programmers, when a lot of time is spent debugging, and when internal APIs become essential, static typing begins to show its strength. People can't just change interfaces willy-nilly and expect everyone else to adapt; the compiler catches this.
