As Dave notes, hardware load balancing works just fine in front of CF Std servers. The sticky session thing really is key, though, if you have any sort of session management in your applications. Another option to sticky sessions on the LB is to convert session structs to client structs within the applications, but that can be a bit of refactoring work, of course. If you go that route, just be sure to save Client vars to the database NOT the Registry, and understand that client scope can't hold complex data types, so structs, arrays, and queries need to be converted to WDDX or JSON or some other serialized format before they can be assigned to a client var.
