How modernization changed HMS London's handling

Was HMS London's handling poor after modernization?

Its handling changed from race-car-like responsiveness to a rally car's need for more anticipation and tolerance of rougher conditions.

HMS London did not simply handle badly after modernization. The race-car-to-rally-car analogy describes a change in character rather than an unsafe ship. The rebuilt cruiser required its crew to anticipate the route and its reactions more carefully. In return, its handling was better suited to the rough conditions of operational service.
