I bought my first pair last month. They are last years model and have the Pro chamois. They were originally $150 or so but I got them at a special deal at an outlet store for like $60. Am considering buying more I love them SO SO SO much.
The bib makes a huge difference! No bunching up around my waist! Also they are cut slimmer than the regular shorts. Normally the XS shorts climb up on me after a while. These are nice and snug. If you like your normal size you might consider trying on 1 larger just to make sure about the leg openings etc.
Also, I am a 32A with a petite torso so they work great on me without the staps being too tight or falling down or anything. I also don't really seem to ever have to pee on the bike so I don't have the usual bib issues...
