True... Though would a Xenon set be necessarily that much better than 15-year-old RX-100? And With Xenon levers I assume I'd have to go with Campy derailleurs - I'd more likely to for Sora levers and keep the existing derailleurs. But I don't like the thumb clicky things for shifting, so that's why I've been looking at Tiagra.
