A520s go on all my bikes. There's a pair for the new bike in the package I have to pick up at the post office tomorrow.
I don't like 700-800 miles of breaking in the bearings, but maybe that means they'll last a really long time.
You should give Looks or SPD-SLs a try on your new blue bike if it is going to be your sporting bike. I'm a big believer in different solutions for different circumstances.
