Has anyone worn these? So far I am pretty happy with my Power 3/4 tights (for cooler rides) and my Oxygen shorts. It sounds like the Xenon shorts are even thinner up-front, so I am thinking maybe I should give them a try, too. But they're $150, so I don't want to invest in them if someone says that the Chamois isn't worth the added cost ($20 more than the Oxygen).
