i personally say go with a random roommate, but that was because i was super lucky. id say its 50/50 that some of my friends are still living with or are good friends with their freshman roommate (and i just graduated UVM) or no longer talk to them and have not talked to them since the end of freshman year.
your call, wait till after orientation and if you meet someone cool there, then go with them, but dont be afraid to have a random roommate.
