Wanted: Civil 3D User Experiences with OpenRoads

I am a Civil 3D user who is not happy with the software. I'd like to hear from C3D users who have experience with OpenRoads. I have Power Civil SS1 so I have some background with Microstation but I haven't used it for plan production since it is old technology and I didn't want to spend time learning the tools. My current workflow is to do my site modeling in Power Civil and export it to Civil 3D via LandXML for pipe design and plan production.

My main concerns are product stability, performance, pipe networks and plan production. Please feel free to share your experience with me in private if you wish.
