Wheels Trek 5.2

[angusp]

I have a 2008 trek 5.2 with Durace, Fizik Antares saddle,Mavic Kysrium Es Wheels, colour Metallic dark Grey. Looking to upgrade wheels as I have got 4 troublefree years and want to keep them as winter wheels. What would people reccomend. Max spend €1200 either deep rim or normal but must be at least as light as current wheel?
