I've had it for about 13 years, and I don't see any reason to change, I find that the violin just keeps responding really well. It changes itself every year; it ages, it goes through all these different environmental changes, and of course, the travelling...It develops on its own, just as any performer does. It's a very stable instrument, so I can rely on it, but at the same time it always shows me a different side of things than I expect.
