Road Wheels & Road Wheel Recommendations?

I need to replace my ksyriums asap.
Got ultegra groupset and was told to get ultegra wheels (ribble is doing them for around 220£ atm).
Is there anything else i should consider? I don't mind spending a bit more if it's worth it.

Shimano WH-RS31 is fine for road racing at your level, spending more won't really acheive anything apart from a sense of loss when you smash them in the inevitable last corner pile up. Ksyriums have such shit aeros that pretty much anything will be a massive improvement.
