Something to consider when buying bibs: How long do you spend in the saddle? I bought the Assos Mille for double centuries, well worth the $200+ when you're going to spend 17 hours in them. PI's and Specialized work well for me on 6 hour or less training rides.
My problem is finding anything that reaches mid thigh or lower. I'm 6'4, 200 lbs. Looks like I'm wearing Daisy Dukes when I pull into a rest stop.
