Which pair of names shall we go with for our twin baby girls coming in October 2010?

I like Lucia Rose and Layla Grace - they both have a nice roll to the saying of the names and they are lovely both for a young child and a woman - I think they're a good choice. The second names, while lovely are both quite a mouthful and quite a bit more formal sounding. Kind of like they should have nannies and be raised not seeing their parents so much or off at boarding school.
