Nice Rb-2. I built one up for my girlfriend as her "I-don't-need-more-than-1-bike". Unfortunately, next to none of it is stock, but it sure is a nice ride.

I wouldn't do moustache bars unless you've tried them out before. They're either love/hate. I love mine. I have a similar setup to Neal's bike posted above except mine is in a bit more aggressive position at the moment. I do have a technomic stem that I am trying to replace it with though... so +1 to what everyone said.
