I dunno...I really don't need to stop that much. Did 75 miles 2 weeks ago and drank 4 bottles and didn't need a pee break. I don't do ultra distance cycling, and it sounds like the OP doesn't either.

Getting a kit on the snug side is more about eliminating chafing and getting improved aerodynamics for racing than it is about being comfortable in lycra. It shouldn't constrict your movement on the bike, but it's not necessarily going to be a particularly comfy outfit to just hang out in.
