After some time of very moderate use I'm a big fan especially of the knickers.
well these were like $115, so not terribly out of my price range at the moment.
i liked the way they fit closer to my knees, theblackbibs ones kind of flare out JUST a little bit. i didn't think i was that skinny. the length of the rapha/blackbibs is the same, so the tan lines are the same. the chamois seems to retain its "form/shape" more, but I haven't worn them as much yet. much more compression on the rapha jawns.
